Math-Polygon (1.00) *****

Works as advertised.

I mangle and decimate large datasets for engineers and scientists to get them in shape to be imported into tools like CAD and Matlab. I had previously written a simple tool which would get rid of all points outside a bounding box; but one of my engineers wanted to be able to specify an arbitrary polygon instead of just a box.

I snipped out my simple box code and dropped in Math::Polygon code. Everything worked perfectly on the very first try, no bugs, bounding a 45M dataset with an irregular 27-vertice poly perfectly (and chopping the dataset itself down to 4.4M).

THANK YOU for this module! There was MUCH wailing and gnashing of teeth when I thought I was going to have to implement this stuff myself. =)
