me wondering how on earth gtk can use the equivalence of a
200 Mhz pentium to figure out that nothing happened?
Well, determinging if two floating point numbers are the same is a non
trivial operation. There can be multiple encodings of, say, 1.3 depending
on how you got there.
I suspect they take a conservative view and always redraw if thye cant tell
thier the same.
Still, the pixmap is fairly small, 20 × 20 perhaps. It shouldn't take
all day :)
