chipmunk debugdraw

[abakoboParticipant]

here’s my chumpmunk debug draw, it has some more features than the one provided with the module:
-rounded corner polys and rounded end segments
-chose between FastDraw and Complete Draw
-complete draw shows sleeping bodies (greyed), contact points, constrains and make a border to each shape so they are not mixed if of the same color.
-a canvas extension for setting a camera by centerpoint, zoom and rotation
