Subject: [PATCH] Use Dove hardware graphics scaler
The theory behind this patch is to render to a smaller area and then use the hardware upscaler to upscale the graphics plane to the destination resolution.
For instance, going into system setting->system->Video output and choosing Graphics scaling to 1.5, will make 1080p resolution to rendering 1/1.5 of it's size (720p).
Rendering becomes much more faster, memory bandwidth on the LCD controller becomes half too.
Using this patch it's now possible to get higher fps on XBMC GUI
