Thanks Zhenyu, I did a quick scan last Thu. and didn't see anything, this 
should help.

And currently, on 965, I've marked tiling as unsupported, which means 
framebuffer compression isn't enabled by default.  You can still force it on 
using "Tiling" "true" and "FramebufferCompression" "true", but there are 
known rendering bugs; hopefully I can fix those soon.

Thanks,
Jesse
