- window: increase minimum size of a window with menus or fix the menu rendering so that it doesn't look odd.

- window: expose contents size. (#1045)
- window: resize from borders and/or all corners. (#822)
- window: GetWindowSize() returns (0,0) when not calculated? (#1045)
- window: refactor IsWindowFocused(), merge all three existing variants, add flags, similar to #1382.
- window: freeze window flag: if not focused/hovered, return false, render with previous ImDrawList. and/or reduce refresh rate.
!- scrolling: allow immediately effective change of scroll after Begin() if we haven't appended items yet.
- scrolling/clipping: separator on the initial position of a window is not visible (cursorpos.y <= clippos.y). (2017-08-20: can't repro)

- drawlist: maintaining bounding box per command would allow to merge draw command when clipping isn't relied on (typical non-scrolling window or non-overflowing column would merge with previous command).
- drawlist: avoid passing null (-9999,+9999) rectangle to end-user, instead perhaps pass rectangle based on io.DisplaySize?
- drawlist: primtiives/helpers to manipulate vertices post submission, so e.g. a quad/rect can be resized to fit later submitted content, _without_ using the ChannelSplit api
- drawlist: non-AA strokes have gaps between points (#593, #288), especially RenderCheckmark().
- main: considering adding an Init() function? some constructs are awkward in the implementation because of the lack of them.
- main: find a way to preserve relative orders of multiple reappearing windows (so an app toggling between "modes" e.g. fullscreen vs all tools) won't lose relative ordering.
- main: IsItemHovered() make it more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes

- shortcuts: programmatically access shortcuts "Focus("&Save"))

- text: proper alignment options in imgui_internal.h
- text wrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (#249)
- text: it's currently impossible to have a window title with "##". perhaps an official workaround would be nice. \ style inhibitor? non-visible ascii code to insert between #?
- text link/url button: underlined. should api expose an ID or use text contents as ID? which colors enum to use?

- font: better vertical centering (based e.g on height of lowercase 'x'?). currently Roboto-Medium size 16 px isn't currently centered.

- nav: esc/enter default behavior for popups, e.g. be able to mark an "ok" or "cancel" button that would get triggered by those keys.
- focus: preserve ActiveId/focus stack state, e.g. when opening a menu and close it, previously selected InputText() focus gets restored (#622)

- inputs: support track pad style scrolling & slider edit.
- misc: make the ImGuiCond values linear (non-power-of-two). internal storage for ImGuiWindow can use integers to combine into flags.

- Add the Dear 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.
- See examples/ folder for standalone sample applications.
- You may be able to grab and copy a ready made imgui_impl_*** file from the examples/.
- When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them.

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.
- 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed.
- 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up.
Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions.
- 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency.
