Date: Mon, 17 Nov 2003 21:59:24 -0800 From: Pete Shinners Subject: [SDL] directfb cursor patch here is a quick and dirty patch that allows directfb to change the visibility of the cursor. this display backend still has no way to change the actual cursor shape, but being able to set the cursor visibility is a simple change that should offer some benefits. the code was largely based on the cursor code for other sdl backends. and this documentation. http://directfb.org/documentation/DirectFB_Reference/IDirectFBDisplayLayer_SetCursorOpacity.html
