Opening and closing the property bin doesnt work, possibly because the
rotopaint node is inside a gizmo. Also, seems like a big waste of cpu
cycles.

Changing frames does work in the sense that i can change it to ANOTHER
frame and the shape updates correctly, but if i change it back to the frame
i was on, then i guess nukes clever caching set everything back to black
again.

Setting visibility doesnt do anything either.

Now, the weird thing is: the frame does actually update correctly by
itself, something like 5 seconds later. as if some timed redraw of the
window forces the redraw.

back to the drawing table...
