Wasn't there a discussion recently about building a region
from a pixmap - i believe that this was on a thread that mel
instigated concerning getting the size of a letter.

If such a routine exists then andy would only need to draw his arc in
an offscreen world, convert to a region, do an offset for the place
in the window where the arc originally exists, and voilà, test the
click with ptinrgn to see if the arc was clicked. Sounds like a mouth
full, but should be quite quick... if he can find the adequate
routine.
