Subject: [PATCH] wayland: Fix SDL_SetWindowSize() being dropped right after
exiting fullscreen
If we get a SDL_SetWindowSize() call right after SDL_SetWindowFullscreen() but
before we've gotten a new configure event from the compositor, the attempt to
set our window size will silently fail (when libdecor is enabled).
Fix this by remembering that we need to commit a new size, so we can do that
in decoration_frame_configure().
