[Newbies] Re: PolygonMorph intersection

[S Hangal]

Thanks, Jerome - have filed the issue in Mantis.

I'm looking for the easiest way to figure out if polygon A is contained
inside polygon B.

One way to do this is by checking if polygon A intersects any segments of B
and any one of A's vertices lies inside B.
is there a better way ?

Thanks,

-sgh
