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.
