The forbidden topic: Glamo OpenGL

The biggest usability issue with the graphical performance on the Moko
is scrolling/clipping graphics.

If we had the ability to upload an image to the glamo, clip it, and
then pan it in the clip rectangle, a lot of the perceived slowness
wouldn't be a problem.   As long as the controls were visually
responsive, they can have old state.  People can manage with controls
that show old data, as long as they respond when you interact with

A few custom GTK widgets that manage the glamo for this sort of thing
(e.g. the large scroll window for applications, etc) would likely
result in worlds of improvement.

.. or, something fancier... but I think this'd be a great step forward.
