-The program can be compiled either with the available Makefile or with CMake.
+The program requires glfw3 (modern lightweight and portable library for managing
+OpenGL contexts, windows and inputs, similar to glut but better!).

+// - (Step 2: dummy step only required if an explicit items_height was passed to constructor or Begin() and user call Step(). Does nothing and switch to Step 3.)

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.
+
+ - 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!

FREQUENTLY ASKED QUESTIONS (FAQ), TIPS
======================================

+ 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.
+
+ Q: How do I update to a newer version of ImGui?
+ A: Overwrite the following files:
+ imgui.cpp
+ imgui.h
+ imgui_demo.cpp
+ imgui_draw.cpp
+ imgui_internal.h
+ stb_rect_pack.h
+ stb_textedit.h
+ stb_truetype.h
+ Don't overwrite imconfig.h if you have made modification to your copy.
+ Check the "API BREAKING CHANGES" sections for a list of occasional API breaking changes. If you have a problem with a function, search for its name
+ in the code, there will likely be a comment about it. Please report any issue to the GitHub page!
+
+
+ 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,y1,x2,y2) and NOT as (x1,y1,width,height).
+
+ Q: Can I have multiple widgets with the same label? Can I have widget without a label? (Yes)
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 an 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"
- - Elements that are not clickable, such as Text() items don't need an ID.
-
- 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:
+ - 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.
+ 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.
+ - 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##0"); // Label = "Play", ID = hash of "Play##0"
- Button("Play##1"); // Label = "Play", ID = hash of "Play##1" (different from above)
+ 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:
- - occasionally (rarely) you might want change a label while preserving a constant ID. This allows you to animate labels.
- use "###" to pass a label that isn't part of ID:
+ Checkbox("##On", &b); // Label = "", ID = hash of "##On" (no label!)
- Button("Hello###ID"; // Label = "Hello", ID = hash of "ID"
- Button("World###ID"; // Label = "World", ID = hash of "ID" (same as above)
+ - 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:
- - use PushID() / PopID() to create scopes and avoid ID conflicts within the same Window.
- this is the most convenient way of distinguish 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 addition of everything in the ID stack!
+ Button("Hello###ID"; // Label = "Hello", ID = hash of "ID"
+ Button("World###ID"; // Label = "World", ID = hash of "ID" (same as above)

- Q: Why is my text output blurry?
- A: In your Render function, try translating your projection matrix by (0.5f,0.5f) or (0.375f,0.375f)
+ Q: How can I tell when ImGui wants my mouse/keyboard inputs and when I can pass them to my application?
+ A: You can read the 'io.WantCaptureXXX' flags in the ImGuiIO structure. Preferably read them after calling ImGui::NewFrame() to avoid those flags lagging by one frame, but either should be fine.
+ 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.WantInputsCharacters' is set to may want to notify your OS to popup an on-screen keyboard, if available.
+ ImGui is tracking dragging and widget activity that may occur outside the boundary of a window, so 'io.WantCaptureMouse' is a more accurate and complete than testing for ImGui::IsMouseHoveringAnyWindow().
+ (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 file you want:
- io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
- io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
+ ImGuiIO& io = ImGui::GetIO();
+ io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
+ io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
Q: How can I load multiple fonts?
A: Use the font atlas to pack them into a single texture:
-
- 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
-
- Q: How can I render and input Chinese, Japanese, Korean characters?
- A: When loading a font, pass custom Unicode ranges to specify the glyphs to load. ImGui will support UTF-8 encoding across the board.
- Character input depends on you passing the right character code to io.AddInputCharacter(). The example applications do that.
-
- io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, io.Fonts->GetGlyphRangesJapanese()); // Load Japanese characters
- io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()

+
+ 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.
+ All your strings needs to use UTF-8 encoding. 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.
+ In C++11 you can encode a string literal in UTF-8 by using the u8"hello" syntax. Otherwise you can convert yourself to UTF-8 or load text data from file already saved as UTF-8.
+ You can also try to remap your local codepage characters to their Unicode codepoint using font->AddRemapChar(), but international users may have problems reading/editing your source code.
+

+ io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
+ io.ImeWindowHandle = MY_HWND; // To input using Microsoft IME, give ImGui the hwnd of your application
+
+ As for text input, depends on you passing the right character code to io.AddInputCharacter(). The example applications do that.
+
+ 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.
- 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.

+ - input text: add ImGuiInputTextFlags_EnterToApply? (off #218)
+ - input text: add discard flag (e.g. ImGuiInputTextFlags_DiscardActiveBuffer) or make it easier to clear active focus for text replacement during edition (#725)
+ - input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc).
+ - input text multi-line: way to dynamically grow the buffer without forcing the user to initially allocate for worse case (follow up on #200)
+ - input text multi-line: line numbers? status bar? (follow up on #200)
+ - input text multi-line: behave better when user changes input buffer while editing is active (even though it is illegal behavior). namely, the change of buffer can create a scrollbar glitch (#725)
+ - input text: allow centering/positioning text so that ctrl+clicking Drag or Slider keeps the textual value at the same pixel position.
- input number: optional range min/max for Input*() functions
- input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled)

- - input number: non-decimal input.
+ - input number: applying arithmetics ops (+,-,*,/) messes up with text edit undo stack.
+ - button: provide a button that looks framed.
- text: proper alignment options
- - layout: horizontal layout helper (github issue #97)
+ - image/image button: misalignment on padded/bordered button?
+ - image/image button: parameters are confusing, image() has tint_col,border_col whereas imagebutton() has bg_col/tint_col. Even thou they are different parameters ordering could be more consistent. can we fix that?
+ - layout: horizontal layout helper (#97)
+ - layout: horizontal flow until no space left (#404)
- layout: more generic alignment state (left/right/centered) for single items?
- layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 layout code. item width should include frame padding.
- - columns: separator function or parameter that works within the column (currently Separator() bypass all columns)
- - columns: declare column set (each column: fixed size, %, fill, distribute default size among fills)

+ - combo: sparse combo boxes (via function call?) / iterators
- combo: contents should extends to fit label if combo widget is small
+ - combo/listbox: keyboard control. need InputText-like non-active focus + key handling. considering keyboard for custom listbox (pr #203)
- listbox: multiple selection
- listbox: user may want to initial scroll to focus on the one selected value?
- ! menubar, menus
- - tabs
- - gauge: various forms of gauge/loading bars widgets
- - color: better color editor.
+ - listbox: keyboard navigation.
+ - listbox: scrolling should track modified selection.
+!- popups/menus: clarify usage of popups id, how MenuItem/Selectable closing parent popups affects the ID, etc. this is quite fishy needs improvement! (#331, #402)
+ - popups: add variant using global identifier similar to Begin/End (#402)
+ - popups: border options. richer api like BeginChild() perhaps? (#197)
+ - tooltip: tooltip that doesn't fit in entire screen seems to lose their "last preferred button" and may teleport when moving mouse
+ - menus: local shortcuts, global shortcuts (#456, #126)
+ - menus: icons
+ - menus: menubars: some sort of priority / effect of main menu-bar on desktop size?
+ - menus: calling BeginMenu() twice with a same name doesn't seem to append nicely
+ - statusbar: add a per-window status bar helper similar to what menubar does.
+ - tabs (#261, #351)
+ - separator: separator on the initial position of a window is not visible (cursorpos.y <= clippos.y)
+!- color: the color helpers/typing is a mess and needs sorting out.
+ - color: add a better color picker (#346)
+ - node/graph editor (#306)
+ - pie menus patterns (#434)
+ - drag'n drop, dragging helpers (carry dragging info, visualize drag source before clicking, drop target, etc.) (#143, #479)
+ - plot: PlotLines() should use the polygon-stroke facilities (currently issues with averaging normals)
- plot: make it easier for user to draw extra stuff into the graph (e.g: draw basis, highlight certain points, 2d plots, multiple plots)
- plot: "smooth" automatic scale over time, user give an input 0.0(full user scale) 1.0(full derived from value)
- plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID)
- - file selection widget -> build the tool in our codebase to improve model-dialog idioms
- slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
- slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar).
- slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate.
- - text edit: clean up the mess caused by converting UTF-8 <> wchar. the code is rather inefficient right now.
- - text edit: centered text for slider as input text so it matches typical positioning.
- - text edit: flag to disable live update of the user buffer.
- - text edit: field resize behavior - field could stretch when being edited? hover tooltip shows more text?
- - text edit: add multi-line text edit
- - tree: add treenode/treepush int variants? because (void*) cast from int warns on some platforms/settings
+ - slider: tint background based on value (e.g. v_min -> v_max, or use 0.0f either side of the sign)
+ - slider & drag: int data passing through a float
+ - drag float: up/down axis
+ - drag float: added leeway on edge (e.g. a few invisible steps past the clamp limits)
+ - tree node / optimization: avoid formatting when clipped.
+ - tree node: tree-node/header right-most side doesn't take account of horizontal scrolling.
+ - tree node: add treenode/treepush int variants? not there because (void*) cast from int warns on some platforms/settings?
+ - tree node: try to apply scrolling at time of TreePop() if node was just opened and end of node is past scrolling limits?
+ - tree node / selectable render mismatch which is visible if you use them both next to each other (e.g. cf. property viewer)
+ - tree node: tweak color scheme to distinguish headers from selected tree node (#581)
+ - textwrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (#249)
- settings: write more decent code to allow saving/loading new fields
- settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file
- ! style: store rounded corners in texture to use 1 quad per corner (filled and wireframe). so rounding have minor cost.
- - style: checkbox: padding for "active" color should be a multiplier of the
- - style: colorbox not always square?
+ - style: add window shadows.
+ - style/optimization: store rounded corners in texture to use 1 quad per corner (filled and wireframe) to lower the cost of rounding.
+ - style: color-box not always square?
+ - style: a concept of "compact style" that the end-user can easily rely on (e.g. PushStyleCompact()?) that maps to other settings? avoid implementing duplicate helpers such as SmallCheckbox(), etc.
+ - style: try to make PushStyleVar() more robust to incorrect parameters (to be more friendly to edit & continues situation).
+ - style: global scale setting.
+ - style: WindowPadding needs to be EVEN needs the 0.5 multiplier probably have a subtle effect on clip rectangle
- text: simple markup language for color change?
+ - font: dynamic font atlas to avoid baking huge ranges into bitmap and make scaling easier.
+ - font: small opt: for monospace font (like the defalt one) we can trim IndexXAdvance as long as trailing value is == FallbackXAdvance
+ - font: add support for kerning, probably optional. perhaps default to (32..128)^2 matrix ~ 36KB then hash fallback.
+ - font: add a simpler CalcTextSizeA() api? current one ok but not welcome if user needs to call it directly (without going through ImGui::CalcTextSize)
+ - font: fix AddRemapChar() to work before font has been built.
- log: LogButtons() options for specifying depth and/or hiding depth slider
- log: have more control over the log scope (e.g. stop logging when leaving current tree node scope)
- log: be able to log anything (e.g. right-click on a window/tree-node, shows context menu? log into tty/file/clipboard)

// ImGui GLFW binding with OpenGL
+// In this binding, ImTextureID is used to store an OpenGL 'GLuint' texture identifier. Read the FAQ about ImTextureID in imgui.cpp.
+
