Add the flag "--suspend-when-occluded" to testgl, testgles2, and testsprite, which, when used, will suspend rendering and throttle the event loop when the occlusion flag is set on the window.
Adds the SDL_EVENT_WINDOW_OCCLUDED events and the window flag SDL_WINDOW_OCCLUDED to report when the window occlusion state has changed, so that the application can take appropriate measures, as it may wish to suspend drawing, throttle, or otherwise behave in a more energy efficient manner when the window is not visible. When the window is no longer occluded, the SDL_EVENT_WINDOW_EXPOSED event is sent and the occlusion flag is cleared.
This is handled on macOS via the window occlusion state event (available as of 10.9), and via the xdg-shell protocol on Wayland (version 6, wayland-protocols 1.32, passed through in libdecor 0.1.2).
The gamepad vs joystick events always happen in this order:
SDL_EVENT_JOYSTICK_ADDED
SDL_EVENT_GAMEPAD_ADDED
SDL_EVENT_GAMEPAD_REMAPPED
SDL_EVENT_GAMEPAD_REMOVED
SDL_EVENT_JOYSTICK_REMOVED
Whenever a mapping is changed, any controller affected by that mapping will generate a gamepad event. You will only get one SDL_EVENT_GAMEPAD_REMAPPED event per controller per batch of mapping changes, where SDL_AddGamepadMappingsFromFile() and SDL_AddGamepadMapping() are each a batch of changes.
This allows the controllers to report that they have sensors and enhanced capabilities, but not actually switch into enhanced mode (breaking DirectInput) unless the application tries to use them.
In this case we know the controller has been on for a while and the Bluetooth connection LED cycle is complete.
Also fixed the timestamp being zero the first time it is checked
Also renamed most cases of SDL_GAMEPAD_TYPE_UNKNOWN to SDL_GAMEPAD_TYPE_STANDARD, and SDL_GetGamepadType() will return SDL_GAMEPAD_TYPE_UNKNOWN only if the gamepad is invalid.
Removing SDL_GAMEPAD_TYPE_VIRTUAL allows a virtual controller to emulate another gamepad type. The other controller types can be treated as generic controllers by applications without special glyph or functionality treatment.
