Perhaps in the short term a boolean (exposed or not...I'd lean toward
not) would suit. The big isue is lack of composition support. The
Frame currently "slides in" about 1/2 as fast as I'd like it to, and
choppily at that. With composition we could get smooth motion and
also speed it up significantly. (The only reason it's so slow now, I
believe, is because without composition we can't draw frames fast
enough to convey the motion unless we increase the length of the
