I got a crash in the ATI display driver in accelerated compositing mode, which resulted in a Windows blue screen.
This patch is a speculative fix for the crash; a call to use antialiasing when drawing a texture is removed.
I haven't seen the crash after making this change, and I don't think antialiasing is really needed.
It is taken from the GTK implementation, and I can't see any visual differences after removing the call.
Accelerated compositing should also be faster when not doing antialiasing.
