annotate docs/man3/SDL_WasInit.3 @ 3896:1a327643e741 SDL-1.2
X11 backend: tell app that mouse focus has been obtained when grabbing the
input. This allows us to enable DGA mode, even when the system cursor was
outside of the window when the grab was initiated.
Fixes Bugzilla #299, which has a more detailed explanation of the issue.
