void evaluate

[package]

Calculates flat path points for current segment of the source shape.

Line segment is flat by itself. Flatness of quad and cubic curves evaluated by getFlatnessSq() method. Curves subdivided until current flatness is bigger than user defined and subdivision limit isn't exhausted. Single source segment translated to series of buffer points. The less flatness the bigger serries. Every currentSegment() call extract one point from the buffer. When series completed evaluate() takes next source shape segment.
