improve video performance to minimize the tearing effect seen in 720p movies

always rescale videos to their target size using copybit during yuv->rgb
conversion. this improves performance of the GPU pass and doesn't require
linear filtering to be enabled. Also always use 16-bits buffers.

the average processing time for 720p dropped from ~50ms to ~30ms
