Tamito Kajiyama 716803c0a0 Fix for Sinus Displacement and 2D Offset stroke geometry modifiers. ... These modifiers were not working properly when they were applied to strokes whose backbone was already modified by other geometry shaders. This problem was due to the use of Normal2DF0D that compute 2D vertex normals based on the underlying FEdges up on which initial stroke geometry is defined. Now vertex normals are computed on the basis of modified stroke vertices. A helper function 'stroke_normal' for computing normals of stroke vertices was added to the 'freestyle.utils' API module.		2014-04-11 15:16:46 +09:00
