No. The YUV planes are already exposed via Xv (usually adaptor=1) and
YUV->RGB conversion on the GPU (so that it works under a compositer
etc) on the other adaptor; both of them support scaling, but the hw
scaling for YUV planes uses a higher quality filter. Atomic modesestting
doesn't yet expose those planes.
