Could you post an example of your polygons; and state the bounds for the overall coordinate space please.

I believe that there is a way to do this 1 or even 2 magnitudes faster.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
