Subject: Patch for RISC OS cursor palette handling in SDL
Date: Mon, 07 Nov 2005 09:14:15 -0800
The mouse cursor palette was not correctly
restored on RISC OS if the system was using
anything but the default mouse colours.
Additionally I've modifed the order the wait
for vsync is called as it should be after the
screen bank switching.
