Simple polygons fail triangulation about poly2tri

[GoogleCodeExporter]

This must be the result of some bug. They are simple polygons and there is no 
issues triangulation them with the Java version.

C++ has no problem triangulating. See attached screenshots.

Thank you both for verifying this for me. I'll have to go over my code again.

Ok, I'm officially an idiot. Turns out to get it to compile for MSVC I added 
the following:

#ifndef M_PI
#define M_PI 3.1415926535897932384626433832795
#endif

#ifndef M_PI_2
#define M_PI_2 6.283185307179586476925286766558
#endif

And clearly M_PI_2 is meant to be PI / 2 not PI * 2. Sorry for wasting your 
time!

np. I know of one more that did this error. There should probably be a comment 
or something about this in the code.

I usually name such fields PI_DIV_2 to avoid confusion.

OK, I'll change M_PI_2 to PI_DIV_2 to avoid confusion.... thanks for the catch!
