[Spice-devel] Support for new Composite commands

[Søren Sandmann]

The following patch sets spanning spice, spice-common, spice-protocol
and spice-gtk implement support for the following new features:

    - a new A8 surface format
    - a new Composite command

The Composite command is useful for implementing render suport in the
X11 guest driver. There are some details about the command in the
spice-protocol patch.

I have a version of the X driver that makes use of this, and I will send
those patches for review once they are ready:

Feel free to play with it, but note that there are a few known bugs that
among other things cause it to run out of video memory.


Thanks,
Soren
