Properly initializing each plane to their full vertical resolution would
require to actually compute it based on the image format.

vs. the Y plane. So using the full image height to initialize the UV plane
will obviously lead to a buffer overflow. Likewise for other YUV format.

and not necessarily the whole thing, it is fine to initializ the first
line only. Besides, the target surface is not rendered either.
