I think this assertion is showing up another bug or odd behaviour in the driver
(it doesn't happen on ATI or nvidia, and some versions of the Intel driver
don't show it). The assertion means that when we draw the pick buffer (to
detect what actor the mouse is over), we're getting a colour back from
glReadPixels that doesn't correspond to any actor on the stage - i.e. a colour
that we didn't draw. Perhaps it could be related to this?

I used to get this assertion, but since updating to git drivers, I can't
reproduce it (but I've not updated in the last few weeks, as tracking git X
bits and packaging them is a huge pain and I've not been working on things that
are critically affected by these bugs).

Attached is a patch (applies against 0.8 branch) that dumps the pick buffer to
/tmp when this assertion is fired. This may help to debug that problem; if I
can reproduce it on any of my machines, I'll see what I can find out.
