Patch against xvimagesink.c blob 818ffd2b1ef62713f79f093b8d2746a1203c70a9

I use a variant of this patch against gstreamer 0.10.18. I forward-ported the
patch to the current head, though I haven't compiled/tested it there (sorry!
Don't have an appropriate dev environment set up right now).

It's not especially clear from this version of the patch, but the intent is to
move the "calculate the expected size.  This is only for sanity checking..."
block before the call to XvShmCreateImage. I calculate a
rounded_width/rounded_height value in that block, then pass the rounded values
to XvShmCreateImage. Passing the rounded_width/rounded_height values to
XvShmCreateImage fixes the problem in my testing.
