I would need to get at canvas pixel color under certain moving widget or
better (= faster?) colors/"types" of underlying static widgets that are
of polygon shape (not rectangle).
How to arrange it without using higher math that must have to compute
actual distance of each of point on a polygon?
It seems to me that in my "again and again repainting canvas" script the
rendering is slowing down as the time goes.
It is visible even after 10 seconds.
Any idea why?
