I might be tempted to leave out any support of 10- or 12-bit formats for now,
and do that separately from HEVC decoding support. (Including the related
VDP_DECODER_PROFILE_HEVC_MAIN_* values.)

I say this because once you expand VdpChromeType to support 10- and 12-bit
formats, you'll probably also want to expand VdpYCbCrFormat to allow surface
reads/write from 10- and 12-bit surfaces, and extend VdpVideoMixerCreate()
so it can be told which surface bit-depth it should operate on (along with
new associated query APIs). That probably requires a bit more thought;
perhaps not something you want to throw into the basic HEVC support patch
at the last minute?
