- MISSION STATEMENT
- =================
-
- - Easy to use to create code-driven and data-driven tools
- - Easy to use to create ad hoc short-lived tools and long-lived, more elaborate tools
- - Easy to hack and improve
- - Minimize screen real-estate usage
- - Minimize setup and maintenance
- - Minimize state storage on user side
- - Portable, minimize dependencies, run on target (consoles, phones, etc.)
- - Efficient runtime and memory consumption (NB- we do allocate when "growing" content - creating a window / opening a tree node for the first time, etc. - but a typical frame won't allocate anything)
-
- Designed for developers and content-creators, not the typical end-user! Some of the weaknesses includes:
- - Doesn't look fancy, doesn't animate
- - Limited layout features, intricate layouts are typically crafted in code
-
-
- END-USER GUIDE
- ==============
-
- - Double-click title bar to collapse window
- - Click upper right corner to close a window, available when 'bool* p_open' is passed to ImGui::Begin()
- - Click and drag on lower right corner to resize window
- - Click and drag on any empty space to move window
- - Double-click/double-tap on lower right corner grip to auto-fit to content
- - TAB/SHIFT+TAB to cycle through keyboard editable fields
- - Use mouse wheel to scroll
- - Use CTRL+mouse wheel to zoom window contents (if io.FontAllowScaling is true)
- - CTRL+Click on a slider or drag box to input value as text
- - Text editor:
-   - Hold SHIFT or use mouse to select text.
-   - CTRL+Left/Right to word jump
-   - CTRL+Shift+Left/Right to select words
-   - CTRL+A our Double-Click to select all
-   - CTRL+X,CTRL+C,CTRL+V to use OS clipboard
-   - CTRL+Z,CTRL+Y to undo/redo
-   - ESCAPE to revert text to its original value
-   - You can apply arithmetic operators +,*,/ on numerical values. Use +- to subtract (because - would set a negative value!)
-   - Controls are automatically adjusted for OSX to match standard OSX text editing operations.

-
- PROGRAMMER GUIDE
- ================
-
- READ FIRST
-
- - Read the FAQ below this section!
- - Your code creates the UI, if your code doesn't run the UI is gone! == very dynamic UI, no construction/destructions steps, less data retention on your side, no state duplication, less sync, less bugs.
- - Call and read ImGui::ShowTestWindow() for demo code demonstrating most features.
- - You can learn about immediate-mode gui principles at http://www.johno.se/book/imgui.html or watch http://mollyrocket.com/861
-
- HOW TO UPDATE TO A NEWER VERSION OF IMGUI
-
- - Overwrite all the sources files except for imconfig.h (if you have made modification to your copy of imconfig.h)
- - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes. 
-   If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed from the public API.
-   If you have a problem with a missing function/symbols, search for its name in the code, there will likely be a comment about it. 
-   Please report any issue to the GitHub page!
- - Try to keep your copy of dear imgui reasonably up to date.
-
- GETTING STARTED WITH INTEGRATING IMGUI IN YOUR CODE/ENGINE
-
- - Add the ImGui source files to your projects, using your preferred build system. It is recommended you build the .cpp files as part of your project and not as a library.
- - You can later customize the imconfig.h file to tweak some compilation time behavior, such as integrating imgui types with your own maths types.
- - See examples/ folder for standalone sample applications. To understand the integration process, you can read examples/opengl2_example/ because it is short, 
-   then switch to the one more appropriate to your use case.
- - You may be able to grab and copy a ready made imgui_impl_*** file from the examples/.
- - When using ImGui, your programming IDE if your friend: follow the declaration of variables, functions and types to find comments about them.
-
- - Init: retrieve the ImGuiIO structure with ImGui::GetIO() and fill the fields marked 'Settings': at minimum you need to set io.DisplaySize (application resolution).
-   Later on you will fill your keyboard mapping, clipboard handlers, and other advanced features but for a basic integration you don't need to worry about it all.
- - Init: call io.Fonts->GetTexDataAsRGBA32(...), it will build the font atlas texture, then load the texture pixels into graphics memory.
- - Every frame:
-    - In your main loop as early a possible, fill the IO fields marked 'Input' (e.g. mouse position, buttons, keyboard info, etc.)
-    - Call ImGui::NewFrame() to begin the imgui frame
-    - You can use any ImGui function you want between NewFrame() and Render()
-    - Call ImGui::Render() as late as you can to end the frame and finalize render data. it will call your io.RenderDrawListFn handler.
-       (if you don't need to render, you still need to call Render() and ignore the callback, or call EndFrame() instead. if you call neither some aspects of windows focusing/moving will appear broken.)
- - All rendering information are stored into command-lists until ImGui::Render() is called.
- - ImGui never touches or knows about your GPU state. the only function that knows about GPU is the RenderDrawListFn handler that you provide.
- - Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render" phases of your own application.
- - Refer to the examples applications in the examples/ folder for instruction on how to setup your code.
- - A minimal application skeleton may be:
-
-     // Application init
-     ImGuiIO& io = ImGui::GetIO();
-     io.DisplaySize.x = 1920.0f;
-     io.DisplaySize.y = 1280.0f;
-     io.RenderDrawListsFn = MyRenderFunction;  // Setup a render function, or set to NULL and call GetDrawData() after Render() to access the render data.
-     // TODO: Fill others settings of the io structure later.
-
-     // Load texture atlas (there is a default font so you don't need to care about choosing a font yet)
-     unsigned char* pixels;
-     int width, height;
-     io.Fonts->GetTexDataAsRGBA32(pixels, &width, &height);
-     // TODO: At this points you've got the texture data and you need to upload that your your graphic system:
-     MyTexture* texture = MyEngine::CreateTextureFromMemoryPixels(pixels, width, height, TEXTURE_TYPE_RGBA)
-     // TODO: Store your texture pointer/identifier (whatever your engine uses) in 'io.Fonts->TexID'. This will be passed back to your via the renderer.
-     io.Fonts->TexID = (void*)texture;
-
-     // Application main loop
-     while (true)
-     {
-        // Setup low-level inputs (e.g. on Win32, GetKeyboardState(), or write to those fields from your Windows message loop handlers, etc.)
-        ImGuiIO& io = ImGui::GetIO();
-        io.DeltaTime = 1.0f/60.0f;
-        io.MousePos = mouse_pos;
-        io.MouseDown[0] = mouse_button_0;
-        io.MouseDown[1] = mouse_button_1;
-
-        // Call NewFrame(), after this point you can use ImGui::* functions anytime
-        ImGui::NewFrame();
-
-        // Most of your application code here
-        MyGameUpdate(); // may use any ImGui functions, e.g. ImGui::Begin("My window"); ImGui::Text("Hello, world!"); ImGui::End();
-        MyGameRender(); // may use any ImGui functions as well!
-     
-        // Render & swap video buffers
-        ImGui::Render();
-        SwapBuffers();
-     }
-
- - A minimal render function skeleton may be:
-
-    void void MyRenderFunction(ImDrawData* draw_data)(ImDrawData* draw_data)
-    {
-       // TODO: Setup render state: alpha-blending enabled, no face culling, no depth testing, scissor enabled
-       // TODO: Setup viewport, orthographic projection matrix
-       // TODO: Setup shader: vertex { float2 pos, float2 uv, u32 color }, fragment shader sample color from 1 texture, multiply by vertex color.
-       for (int n = 0; n < draw_data->CmdListsCount; n++)
-       {
-          const ImDrawVert* vtx_buffer = cmd_list->VtxBuffer.Data;  // vertex buffer generated by ImGui
-          const ImDrawIdx* idx_buffer = cmd_list->IdxBuffer.Data;   // index buffer generated by ImGui
-          for (int cmd_i = 0; cmd_i < cmd_list->CmdBuffer.Size; cmd_i++)
-          {
-             const ImDrawCmd* pcmd = &cmd_list->CmdBuffer[cmd_i];
-             if (pcmd->UserCallback)
-             {
-                 pcmd->UserCallback(cmd_list, pcmd);
-             }
-             else
-             {
-                 // Render 'pcmd->ElemCount/3' texture triangles
-                 MyEngineBindTexture(pcmd->TextureId);
-                 MyEngineScissor((int)pcmd->ClipRect.x, (int)pcmd->ClipRect.y, (int)(pcmd->ClipRect.z - pcmd->ClipRect.x), (int)(pcmd->ClipRect.w - pcmd->ClipRect.y));
-                 MyEngineDrawIndexedTriangles(pcmd->ElemCount, sizeof(ImDrawIdx) == 2 ? GL_UNSIGNED_SHORT : GL_UNSIGNED_INT, idx_buffer, vtx_buffer);
-             }
-             idx_buffer += pcmd->ElemCount;
-          }
-       }
-    }
-
- - The examples/ folders contains many functional implementation of the pseudo-code above.
- - When calling NewFrame(), the 'io.WantCaptureMouse'/'io.WantCaptureKeyboard'/'io.WantTextInput' flags are updated. 
-   They tell you if ImGui intends to use your inputs. So for example, if 'io.WantCaptureMouse' is set you would typically want to hide 
-   mouse inputs from the rest of your application. Read the FAQ below for more information about those flags.

- API BREAKING CHANGES
- ====================
-
- Occasionally introducing changes that are breaking the API. The breakage are generally minor and easy to fix.
- Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code.
- Also read releases logs https://github.com/ocornut/imgui/releases for more details.
-
- - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your binding if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)".
- - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete).
-                     - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete).
-                     - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete).
- - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency.
- - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix.
- - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame.
- - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely.
- - 2017/08/13 (1.51) - renamed ImGuiCol_Columns*** to ImGuiCol_Separator***. Kept redirection enums (will obsolete).
- - 2017/08/11 (1.51) - renamed ImGuiSetCond_*** types and flags to ImGuiCond_***. Kept redirection enums (will obsolete).
- - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton().
- - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu.
-                     - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options.
-                     - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0,0))'
- - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse
- - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset.
- - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity.
- - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetId() and use it instead of passing string to BeginChild().
- - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it.
- - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc.
- - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully breakage should be minimal.
- - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore. 
-                       If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you. 
-                       However if your TitleBg/TitleBgActive alpha was <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar.
-                       This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color.
-                           ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col)
-                           {
-                               float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a;
-                               return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a);
-                           }
-                       If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color.
- - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext().
- - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection.
- - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen).
- - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDraw::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer.
- - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref github issue #337).
- - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337)
- - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete).
- - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert.
- - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you.
- - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis.
- - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete.
- - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position.
-                       GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side.
-                       GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out!
- - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize
- - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project.
- - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason
- - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure.
-                       you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text.
- - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost.
-                       this necessary change will break your rendering function! the fix should be very easy. sorry for that :(
-                     - if you are using a vanilla copy of one of the imgui_impl_XXXX.cpp provided in the example, you just need to update your copy and you can ignore the rest.
-                     - the signature of the io.RenderDrawListsFn handler has changed!
-                            ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count)
-                       became:
-                            ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data).
-                              argument   'cmd_lists'        -> 'draw_data->CmdLists'
-                              argument   'cmd_lists_count'  -> 'draw_data->CmdListsCount'
-                              ImDrawList 'commands'         -> 'CmdBuffer'
-                              ImDrawList 'vtx_buffer'       -> 'VtxBuffer'
-                              ImDrawList  n/a               -> 'IdxBuffer' (new)
-                              ImDrawCmd  'vtx_count'        -> 'ElemCount'
-                              ImDrawCmd  'clip_rect'        -> 'ClipRect'
-                              ImDrawCmd  'user_callback'    -> 'UserCallback'
-                              ImDrawCmd  'texture_id'       -> 'TextureId'
-                     - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer.
-                     - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!
-                     - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade!
- - 2015/07/10 (1.43) - changed SameLine() parameters from int to float.
- - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete).
- - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount.
- - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence
- - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely be used. Sorry!
- - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete).
- - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete).
- - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons.
- - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened.
- - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same).
- - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50.
- - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API
- - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive.
- - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead.
- - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50.
- - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing
- - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50.
- - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing)
- - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond). Kept inline redirection function until 1.50.
- - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once.
- - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now.
- - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior
- - 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing()
- - 2015/02/01 (1.31) - removed IO.MemReallocFn (unused)
- - 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions.
- - 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader.
-              (1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels.
-                       this sequence:
-                           const void* png_data;
-                           unsigned int png_size;
-                           ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size);
-                           // <Copy to GPU>
-                       became:
-                           unsigned char* pixels;
-                           int width, height;
-                           io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height);
-                           // <Copy to GPU>
-                           io.Fonts->TexID = (your_texture_identifier);
-                       you now have much more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs.
-                       it is now recommended that you sample the font texture with bilinear interpolation.
-              (1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to set io.Fonts->TexID.
-              (1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix)
-              (1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets
- - 2014/12/10 (1.18) - removed SetNewWindowDefaultPos() in favor of new generic API SetNextWindowPos(pos, ImGuiSetCondition_FirstUseEver)
- - 2014/11/28 (1.17) - moved IO.Font*** options to inside the IO.Font-> structure (FontYOffset, FontTexUvForWhite, FontBaseScale, FontFallbackGlyph)
- - 2014/11/26 (1.17) - reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility
- - 2014/11/07 (1.15) - renamed IsHovered() to IsItemHovered()
- - 2014/10/02 (1.14) - renamed IMGUI_INCLUDE_IMGUI_USER_CPP to IMGUI_INCLUDE_IMGUI_USER_INL and imgui_user.cpp to imgui_user.inl (more IDE friendly)
- - 2014/09/25 (1.13) - removed 'text_end' parameter from IO.SetClipboardTextFn (the string is now always zero-terminated for simplicity)
- - 2014/09/24 (1.12) - renamed SetFontScale() to SetWindowFontScale()
- - 2014/09/24 (1.12) - moved IM_MALLOC/IM_REALLOC/IM_FREE preprocessor defines to IO.MemAllocFn/IO.MemReallocFn/IO.MemFreeFn
- - 2014/08/30 (1.09) - removed IO.FontHeight (now computed automatically)
- - 2014/08/30 (1.09) - moved IMGUI_FONT_TEX_UV_FOR_WHITE preprocessor define to IO.FontTexUvForWhite
- - 2014/08/28 (1.09) - changed the behavior of IO.PixelCenterOffset following various rendering fixes

- FREQUENTLY ASKED QUESTIONS (FAQ), TIPS
- ======================================
-
- Q: How can I help?
- A: - If you are experienced enough with ImGui and with C/C++, look at the todo list and see how you want/can help!
-    - Become a Patron/donate! Convince your company to become a Patron or provide serious funding for development time! See http://www.patreon.com/imgui
-
- Q: What is ImTextureID and how do I display an image?
- A: ImTextureID is a void* used to pass renderer-agnostic texture references around until it hits your render function.
-    ImGui knows nothing about what those bits represent, it just passes them around. It is up to you to decide what you want the void* to carry!
-    It could be an identifier to your OpenGL texture (cast GLuint to void*), a pointer to your custom engine material (cast MyMaterial* to void*), etc.
-    At the end of the chain, your renderer takes this void* to cast it back into whatever it needs to select a current texture to render.
-    Refer to examples applications, where each renderer (in a imgui_impl_xxxx.cpp file) is treating ImTextureID as a different thing.
-    (c++ tip: OpenGL uses integers to identify textures. You can safely store an integer into a void*, just cast it to void*, don't take it's address!)
-    To display a custom image/texture within an ImGui window, you may use ImGui::Image(), ImGui::ImageButton(), ImDrawList::AddImage() functions.
-    ImGui will generate the geometry and draw calls using the ImTextureID that you passed and which your renderer can use.
-    It is your responsibility to get textures uploaded to your GPU.
-
- Q: I integrated ImGui in my engine and the text or lines are blurry..
- A: In your Render function, try translating your projection matrix by (0.5f,0.5f) or (0.375f,0.375f).
-    Also make sure your orthographic projection matrix and io.DisplaySize matches your actual framebuffer dimension.
-
- Q: I integrated ImGui in my engine and some elements are clipping or disappearing when I move windows around..
- A: Most likely you are mishandling the clipping rectangles in your render function. Rectangles provided by ImGui are defined as (x1=left,y1=top,x2=right,y2=bottom) and NOT as (x1,y1,width,height).
-
- Q: Can I have multiple widgets with the same label? Can I have widget without a label?
- A: Yes. A primer on the use of labels/IDs in ImGui..
-
-   - Elements that are not clickable, such as Text() items don't need an ID.
-
-   - Interactive widgets require state to be carried over multiple frames (most typically ImGui often needs to remember what is the "active" widget).
-     to do so they need a unique ID. unique ID are typically derived from a string label, an integer index or a pointer.
-
-       Button("OK");        // Label = "OK",     ID = hash of "OK"
-       Button("Cancel");    // Label = "Cancel", ID = hash of "Cancel"
-
-   - ID are uniquely scoped within windows, tree nodes, etc. so no conflict can happen if you have two buttons called "OK" in two different windows
-     or in two different locations of a tree.
-
-   - If you have a same ID twice in the same location, you'll have a conflict:
-
-       Button("OK");
-       Button("OK");           // ID collision! Both buttons will be treated as the same.
-
-     Fear not! this is easy to solve and there are many ways to solve it!
-
-   - When passing a label you can optionally specify extra unique ID information within string itself. This helps solving the simpler collision cases.
-     use "##" to pass a complement to the ID that won't be visible to the end-user:
-
-       Button("Play");         // Label = "Play",   ID = hash of "Play"
-       Button("Play##foo1");   // Label = "Play",   ID = hash of "Play##foo1" (different from above)
-       Button("Play##foo2");   // Label = "Play",   ID = hash of "Play##foo2" (different from above)
-
-   - If you want to completely hide the label, but still need an ID:
-
-       Checkbox("##On", &b);   // Label = "",       ID = hash of "##On" (no label!)
-
-   - Occasionally/rarely you might want change a label while preserving a constant ID. This allows you to animate labels.
-     For example you may want to include varying information in a window title bar (and windows are uniquely identified by their ID.. obviously)
-     Use "###" to pass a label that isn't part of ID:
-
-       Button("Hello###ID";   // Label = "Hello",  ID = hash of "ID"
-       Button("World###ID";   // Label = "World",  ID = hash of "ID" (same as above)
-
-       sprintf(buf, "My game (%f FPS)###MyGame");
-       Begin(buf);            // Variable label,   ID = hash of "MyGame"
-
-   - Use PushID() / PopID() to create scopes and avoid ID conflicts within the same Window.
-     This is the most convenient way of distinguishing ID if you are iterating and creating many UI elements.
-     You can push a pointer, a string or an integer value. Remember that ID are formed from the concatenation of everything in the ID stack!
-
-       for (int i = 0; i < 100; i++)
-       {
-         PushID(i);
-         Button("Click");   // Label = "Click",  ID = hash of integer + "label" (unique)
-         PopID();
-       }
-
-       for (int i = 0; i < 100; i++)
-       {
-         MyObject* obj = Objects[i];
-         PushID(obj);
-         Button("Click");   // Label = "Click",  ID = hash of pointer + "label" (unique)
-         PopID();
-       }
-
-       for (int i = 0; i < 100; i++)
-       {
-         MyObject* obj = Objects[i];
-         PushID(obj->Name);
-         Button("Click");   // Label = "Click",  ID = hash of string + "label" (unique)
-         PopID();
-       }
-
-   - More example showing that you can stack multiple prefixes into the ID stack:
-
-       Button("Click");     // Label = "Click",  ID = hash of "Click"
-       PushID("node");
-       Button("Click");     // Label = "Click",  ID = hash of "node" + "Click"
-         PushID(my_ptr);
-           Button("Click"); // Label = "Click",  ID = hash of "node" + ptr + "Click"
-         PopID();
-       PopID();
-
-   - Tree nodes implicitly creates a scope for you by calling PushID().
-
-       Button("Click");     // Label = "Click",  ID = hash of "Click"
-       if (TreeNode("node"))
-       {
-         Button("Click");   // Label = "Click",  ID = hash of "node" + "Click"
-         TreePop();
-       }
-
-   - When working with trees, ID are used to preserve the open/close state of each tree node.
-     Depending on your use cases you may want to use strings, indices or pointers as ID.
-      e.g. when displaying a single object that may change over time (1-1 relationship), using a static string as ID will preserve your node open/closed state when the targeted object change.
-      e.g. when displaying a list of objects, using indices or pointers as ID will preserve the node open/closed state differently. experiment and see what makes more sense!
-
- Q: How can I tell when ImGui wants my mouse/keyboard inputs VS when I can pass them to my application?
- A: You can read the 'io.WantCaptureMouse'/'io.WantCaptureKeyboard'/'ioWantTextInput' flags from the ImGuiIO structure. 
-    - When 'io.WantCaptureMouse' or 'io.WantCaptureKeyboard' flags are set you may want to discard/hide the inputs from the rest of your application.
-    - When 'io.WantTextInput' is set to may want to notify your OS to popup an on-screen keyboard, if available (e.g. on a mobile phone, or console without a keyboard).
-    Preferably read the flags after calling ImGui::NewFrame() to avoid them lagging by one frame. But reading those flags before calling NewFrame() is also generally ok, 
-    as the bool toggles fairly rarely and you don't generally expect to interact with either ImGui or your application during the same frame when that transition occurs.
-    ImGui is tracking dragging and widget activity that may occur outside the boundary of a window, so 'io.WantCaptureMouse' is more accurate and correct than checking if a window is hovered.
-    (Advanced note: text input releases focus on Return 'KeyDown', so the following Return 'KeyUp' event that your application receive will typically have 'io.WantCaptureKeyboard=false'. 
-     Depending on your application logic it may or not be inconvenient. You might want to track which key-downs were for ImGui (e.g. with an array of bool) and filter out the corresponding key-ups.)
-
- Q: How can I load a different font than the default? (default is an embedded version of ProggyClean.ttf, rendered at size 13)
- A: Use the font atlas to load the TTF/OTF file you want:
-
-      ImGuiIO& io = ImGui::GetIO();
-      io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
-      io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
-
- Q: How can I easily use icons in my application?
- A: The most convenient and practical way is to merge an icon font such as FontAwesome inside you main font. Then you can refer to icons within your strings.
-    Read 'How can I load multiple fonts?' and the file 'extra_fonts/README.txt' for instructions.
-
- Q: How can I load multiple fonts?
- A: Use the font atlas to pack them into a single texture:
-    (Read extra_fonts/README.txt and the code in ImFontAtlas for more details.)
-
-      ImGuiIO& io = ImGui::GetIO();
-      ImFont* font0 = io.Fonts->AddFontDefault();
-      ImFont* font1 = io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
-      ImFont* font2 = io.Fonts->AddFontFromFileTTF("myfontfile2.ttf", size_in_pixels);
-      io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
-      // the first loaded font gets used by default
-      // use ImGui::PushFont()/ImGui::PopFont() to change the font at runtime
-
-      // Options
-      ImFontConfig config;
-      config.OversampleH = 3;
-      config.OversampleV = 1;
-      config.GlyphOffset.y -= 2.0f;      // Move everything by 2 pixels up
-      config.GlyphExtraSpacing.x = 1.0f; // Increase spacing between characters
-      io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, &config);
-
-      // Combine multiple fonts into one (e.g. for icon fonts)
-      ImWchar ranges[] = { 0xf000, 0xf3ff, 0 };
-      ImFontConfig config;
-      config.MergeMode = true;
-      io.Fonts->AddFontDefault();
-      io.Fonts->LoadFromFileTTF("fontawesome-webfont.ttf", 16.0f, &config, ranges); // Merge icon font
-      io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, NULL, &config, io.Fonts->GetGlyphRangesJapanese()); // Merge japanese glyphs
-
- Q: How can I display and input non-Latin characters such as Chinese, Japanese, Korean, Cyrillic?
- A: When loading a font, pass custom Unicode ranges to specify the glyphs to load. 
-
-      // Add default Japanese ranges
-      io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, io.Fonts->GetGlyphRangesJapanese());
-   
-      // Or create your own custom ranges (e.g. for a game you can feed your entire game script and only build the characters the game need)
-      ImVector<ImWchar> ranges;
-      ImFontAtlas::GlyphRangesBuilder builder;
-      builder.AddText("Hello world");                        // Add a string (here "Hello world" contains 7 unique characters)
-      builder.AddChar(0x7262);                               // Add a specific character
-      builder.AddRanges(io.Fonts->GetGlyphRangesJapanese()); // Add one of the default ranges
-      builder.BuildRanges(&ranges);                          // Build the final result (ordered ranges with all the unique characters submitted)
-      io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, ranges.Data);
-
-    All your strings needs to use UTF-8 encoding. In C++11 you can encode a string literal in UTF-8 by using the u8"hello" syntax. 
-    Specifying literal in your source code using a local code page (such as CP-923 for Japanese or CP-1251 for Cyrillic) will NOT work!
-    Otherwise you can convert yourself to UTF-8 or load text data from file already saved as UTF-8.
-
-    Text input: it is up to your application to pass the right character code to io.AddInputCharacter(). The applications in examples/ are doing that.
-    For languages using IME, on Windows you can copy the Hwnd of your application to io.ImeWindowHandle. The default implementation of io.ImeSetInputScreenPosFn() on Windows will set your IME position correctly.
-
- Q: How can I preserve my ImGui context across reloading a DLL? (loss of the global/static variables)
- A: Create your own context 'ctx = CreateContext()' + 'SetCurrentContext(ctx)' and your own font atlas 'ctx->GetIO().Fonts = new ImFontAtlas()' so you don't rely on the default globals.
-
- Q: How can I use the drawing facilities without an ImGui window? (using ImDrawList API)
- A: The easiest way is to create a dummy window. Call Begin() with NoTitleBar|NoResize|NoMove|NoScrollbar|NoSavedSettings|NoInputs flag, zero background alpha, 
-    then retrieve the ImDrawList* via GetWindowDrawList() and draw to it in any way you like.
-    You can also perfectly create a standalone ImDrawList instance _but_ you need ImGui to be initialized because ImDrawList pulls from ImGui data to retrieve the coordinates of the white pixel.
-
- - tip: the construct 'IMGUI_ONCE_UPON_A_FRAME { ... }' will run the block of code only once a frame. You can use it to quickly add custom UI in the middle of a deep nested inner loop in your code.
- - tip: you can create widgets without a Begin()/End() block, they will go in an implicit window called "Debug"
- - tip: you can call Begin() multiple times with the same name during the same frame, it will keep appending to the same window. this is also useful to set yourself in the context of another window (to get/set other settings)
- - tip: you can call Render() multiple times (e.g for VR renders).
- - tip: call and read the ShowTestWindow() code in imgui_demo.cpp for more example of how to use ImGui!

-// dear imgui, v1.52 WIP
-// (demo code)
-
-// Message to the person tempted to delete this file when integrating ImGui into their code base:
-// Don't do it! Do NOT remove this file from your project! It is useful reference code that you and other users will want to refer to.
-// Everything in this file will be stripped out by the linker if you don't call ImGui::ShowTestWindow().
-// During development, you can call ImGui::ShowTestWindow() in your code to learn about various features of ImGui. Have it wired in a debug menu!
-// Removing this file from your project is hindering access to documentation for everyone in your team, likely leading you to poorer usage of the library.
-// Note that you can #define IMGUI_DISABLE_TEST_WINDOWS in imconfig.h for the same effect.
-// If you want to link core ImGui in your public builds but not those test windows, #define IMGUI_DISABLE_TEST_WINDOWS in imconfig.h and those functions will be empty.
-// For any other case, if you have ImGui available you probably want this to be available for reference and execution.
-// Thank you,
-// -Your beloved friend, imgui_demo.cpp (that you won't delete)
-
-// Message to beginner C/C++ programmer about the meaning of 'static': in this demo code, we frequently we use 'static' variables inside functions. 
-// We do this as a way to gather code and data in the same place, make the demo code faster to read, faster to write, and smaller. A static variable persist across calls, 
-// so it is essentially like a global variable but declared inside the scope of the function.
-// It also happens to be a convenient way of storing simple UI related information as long as your function doesn't need to be reentrant or used in threads.
-// This may be a pattern you want to use in your code (simple is beautiful!), but most of the real data you would be editing is likely to be stored outside your function.
