Title: Added rotation with origin point

This is a very small change; I just added this function

- (SPPoint *)rotateBy:(float)angle originX:(float)xc originY:(float)yc;

which rotates the SPPoint with a given origin point - kind of like a pivot point for rotation.

I am also working on a rotated bounds method but that needs much polishing and testing.
