Great! Thanks for getting this done.

The YUV picture code needs a second look. The repeat stuff should be
correct. Repeat, Pad, Reflect should now be working correct with
gradient and normal pictures.

Lars Knoll who wrote the initial gradient code probably wants to have a
look at the gradient updates before they land in the main tree. E.g.
I've temporarily disabled the use of color tables until we have some
code to figure out when they can be used without loss of quality and
when not.

You shouldn't have to use the mangled namespace with Xgl any longer.
