 TL;DR; 
  - Newcomers, read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup ImGui in your codebase.
- - Refer to 'opengl_example' to understand how the library is setup, it is the simplest one.

    The other examples requires more boilerplate and are harder to read.

 At 60 FPS your experience should be pleasant. Consider that OS mouse cursors are typically drawn through 
 a specific hardware accelerated route and may feel smoother than other GPU rendered contents. You may

 to switch to a software rendered cursor when an interactive drag is in progress. 
 Also note that some setup or GPU drivers may be causing extra lag (possibly by enforcing triple buffering), 
 leaving you with no option but sadness/anger (Intel GPU drivers were reported as such).
