Commits on Sep 12, 2024

  1. Feature: Save CPU When Losing Focus 

    TL;DR: Refactor event handling and add performance option

This update saves power without requiring changes to animation and physics animations.

Related issue: nijigenerate/nijigenerate#21

* Refactored the event handling in the `incBeginLoop` function to use a state machine for managing poll and wait modes, reducing CPU usage when the application is not focused.
* Added a new performance option in the settings window called `Render Only When Window Focused`.  Enabling this option stops rendering when the window loses focus, further reducing CPU usage.
* This feature is enabled by default

  2. Pass SDL_WINDOWEVENT to imgui 

    we can see the source code for this in imgui_impl_sdl2.cpp:ImGui_ImplSDL2_ProcessEvent()
https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_sdl2.cpp
imgui will handle SDL_WINDOWEVENT, so we need to pass it to imgui
incGLBackendProcessEvent() would invoke ImGui_ImplSDL2_ProcessEvent()
