   // size y (luminance) plane and half-width, half-height u and v (blue and
   // red chrominance) planes. This method will allocate three lockable surfaces,
   // one for each plane, and return them via the arguments |dst_y|, |dst_u|,
   // and |dst_v|. These surface will be created with an ARGB D3DFORMAT, but
   // should be interpreted as the appropriate single-byte format when locking.
