 @file
 Drawing OpenGL ES primitives.
 - ccDrawPoint, ccDrawPoints
 - ccDrawLine
 - ccDrawRect, ccDrawSolidRect
 - ccDrawPoly, ccDrawSolidPoly
 - ccDrawCircle
 - ccDrawQuadBezier
 - ccDrawCubicBezier
 - ccDrawCatmullRom
 - ccDrawCardinalSpline
 
 You can change the color, point size, width by calling:
 - ccDrawColor4B(), ccDrawColor4F()
 - ccPointSize()
 - glLineWidth()
 
 @warning These functions draws the Line, Point, Polygon, immediately. They aren't batched. If you are going to make a game that depends on these primitives, I suggest creating a batch. Instead you should use DrawNode
