 TL;DR; 
- Newcomers, read 'Programmer guide' imgui.cpp for notes on how to setup ImGui in your codebase.
- Refer to 'opengl_example' to understand how the library is setup, because it is the simplest one.
- Copy the imgui_impl_xxx.cpp/.h files you need if you are using one of provided rendering/IO backends.
- If using different or your own backend, copy opengl_example/imgui_impl_opengl.cpp/.h to get started.

 ImGui is highly portable and only requires a few things to run:
  - Providing mouse/keyboard inputs
- - Load the font atlas texture into GPU memory
+ - Load the font atlas texture into graphics memory
  - Providing a render function to render indexed textured triangles
  - Optional: clipboard support, mouse cursor supports, Windows IME support, etc.
 So this is essentially what those examples are doing + the obligatory cruft for portability.
