Frank Praznik 6204768653 wayland: Don't block on libdecor_dispatch() 
libdecor_dispatch() needs to be called, as libdecor plugins might do some required internal processing within, however care must be taken to avoid double-blocking in the case of a timeout, which can occur if libdecor_dispatch() and the SDL event processing both work on the main Wayland queue. Additionally, assumptions that libdecor will always dispatch the main queue or not process zero-length queues (can occur if a wait is interrupted by the application queueing an event) should not be made, as this behavior is outside the control of SDL and can change.

SDL handles polling for Wayland events and then calls libdecor to do its internal processing and dispatch. If libdecor operates on the main queue, it will dispatch the queued events and the additional wl_display_dispatch_pending() call will be a NOP. If a libdecor plugin uses its own, separate queue, then the wl_display_dispatch_pending() call will ensure that the main queue is always dispatched.

Simple DirectMedia Layer (SDL) Version 2.0

https://www.libsdl.org/

Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.

More extensive documentation is available in the docs directory, starting with README.md

Enjoy!
