I think that your solution on this problem is based on the idea of
reading pixel color of the polygon. in this case, each polygon has
to be drawn with different color number. I understand it will work.
However, i think the detection for multiple(plural) polygons (as you said)
is not possible when they are overlaped, since the color of underneath
polygon is simply erased by top polygon, make it impossible to read the
color of underneath polygon....
Could you explain on this for me?
