cc.DrawingPrimitive()

Drawing primitives Utility Class. this class is base class, it contain some render type version: Canvas, WebGL, DOM.
this class contain some primitive Drawing Method:
- drawPoint
- drawLine
- drawPoly
- drawCircle
- drawQuadBezier
- drawCubicBezier
You can change the color, width and other property by calling these WebGL API:
glColor4ub(), glLineWidth(), glPointSize().
