It appears that the internal YUV format used in the current Tarkin code
uses the same number of bits for all three planes.  I would like to be
able to use the same YUV4MPEG2 format files that Ogg Theora uses.  Since
YUV12 and YUV420 only use 1/4 size planes for U and V, does that mean they
must be upsampled to be usable by Tarkin?  Is there a simpler way to make
Tarkin use the existing format?
