Date: Mon, 18 Feb 2002 16:46:59 +1200 From: Julian Kinraid <jkinraid@clear.net.nz> Subject: Patches for photon port of SDL Hi, A couple more patches for photon and the nto audio. Adds mouse grabbing support, fixed cursor images, unicode keyboard events (though no unicode data on kye release, is that a problem?), hopefully fixing some audio lag problems, and a few other fixes. Thanks, Julian Kinraid
