Earcut polygon triangulation

[Ferhat Kurtulmuş via Digitalmars-d-announce]

For those who are interested in game programming, geospatial 
things, 2D graphics etc. Earcut is a polygon triangulation 
library originally written in js and ported to almost every 
popular language (except D). I was playing around with my hobby 
sdl game and needed to draw some concave polygons. So, I have 
just ported the lib (suitable for betterC). My initial tests 
showed that it is fast that can be used for real-time rendering. 
If you have a function that can draw triangles, you can draw 
concave/convex any polygon which can also have holes.
