This would be also useful for other things like making screenshots or supporting XV extension on the ARM devices even without hardware overlays. With NEON SIMD we can do the scaling and colorspace conversion reasonably fast. There will be no (easy) support for vsync though.
Note: on Allwinner A10 hardware we can also use G2D for the same purpose, but that's a less generic solution. Allwinner A13 does not have G2D.
