There are two codepaths which depends on actual wayland specifics that
the summary fails to mention - vaGet{Surface,Image}BufferWl. Cool
thing is that on my system none of the libva users has references to
either of these two plus the latter isn't even implemented in the
intel driver  ;-)

For the future please document things a bit better ? As is the commit
message is rather misleading.

Thanks
