The compositor can toggle the fullscreen state (via a hotkey or otherwise), so the internal SDL state must be updated accordingly when it does.
When toggling fullscreen via the compositor, SDL will attempt to use the last fullscreen flag explicitly set. If no flag was previously set, SDL_WINDOW_FULLSCREEN will be used if a window video mode was set, otherwise SDL_WINDOW_FULLSCREEN_DESKTOP will be used. If the previous flag was SDL_WINDOW_FULLSCREEN and the window video mode was cleared, it will revert to SDL_WINDOW_FULLSCREEN_DESKTOP.
SDL_Quit() should be the last SDL API that you call before exiting your application, and is intended to clean up all internal state.
If real-life applications are relying on thread-local storage after SDL_Quit() we could potentially add a hint to control this behavior.

DS4Windows can create both emulated Xbox and emulated PS4 controllers, and we don't know which the user has it doing, so don't try to second guess it, just let it do it's thing. Users should follow the remapping software recommendations on when to enable/disable it for various situations.

There is supposedly an OpenGL ES2 target that does not support precision specifiers. However, the existing logic to detect this is currently broken in two ways:
1) There's a typo of the `#ifdef` as `#if`.
2) Checking for `GL_FRAGMENT_PRECISION_HIGH` can not be the correct way to detect this platform. Other targets, including some desktops, will also not have this defined (for various reasons).
Because some of the shader code is missing precision specifiers, and because a default is ONLY provided if `GL_FRAGMENT_PRECISION_HIGH` is set, these other targets break.
Instead of 'hard-coding' the prologue string into shaders in the C source, use our ability to provide a list of strings to `glShaderSource` instead, leaving the determination to run-time.
