Defined in <SDL3/SDL_hints.h>
#define SDL_HINT_QUIT_ON_LAST_WINDOW_CLOSE "SDL_QUIT_ON_LAST_WINDOW_CLOSE"
The variable can be set to the following values:
If there is at least one active system tray icon, SDL_EVENT_QUIT will instead be sent when both the last window will be closed and the last tray icon will be destroyed.
This hint can be set anytime.
