Hello Udo,

This commit introduces support for the more efficient shared memory
image blitting.

I enabled compile time support for this extension, because that
extension exists for more than 10 years. Anyway, we'd need a
./configure check for this. There is already a macro, ENABLE_MIT_SHM,
which removes any reference to the extension from the GTK-AGG glue.

As long as building succeeds there should be no problem as the GUI
will fall back to normal pixmaps should the extension not be available
by the server (especially when the X server is not on the same
computer). Check log messages.

Performance improvement is significant, but depends on the movie being
played. Large stage updates with simple graphics will improve by up to
50% or more, while complex movies (much rendering overhead) will not
play much faster.

I expect a slight improvement for video playback, but I can't test
since YouTube playback does not work anymore for me...

Please test the new GUI...
