Just tested my latest patches on an XO-1. Doesn't seem to be any
degradation in terms of performance.

Great. In my refactoring of the sprite library, get_pixel is much the
same as the one on the canvas and much much more simple.

I hadn't seen this, but will check it out.

Other than looking into the button press issue you've raised, I think
TA-123 is ready to go. I am on the fence about two things:

(1) Maybe release this version (cairo) and make 124 the gtk-3 rebased
on your patches.
(2) Should I add my Physics toolbar plugin to the release or leave it
as a separate install... If you haven't tried it, it is really fun.
But perhaps a distraction?

Cool. Let me know how it goes.
