getBoundsOfCurve(
begx,begy,cp1x,cp1y,cp2x,cp2y,endx,endy):TRectBounds
Calculate bounding box of a cubic Bezier curve Taken from http://jsbin.com/ivomiq/56/edit (no credits available) TODO: can we normalize this with the starting points set at 0 and then translated the bbox?
Parameters
• begx: number
starting point
• begy: number
• cp1x: number
first control point
• cp1y: number
• cp2x: number
second control point
• cp2y: number
• endx: number
end of bezier
• endy: number
Returns
the rectangular bounds
