Line Styles (dashed, dotted, and glow) #641

This PR adds different line styles by generating uv textures along stroke paths and then applying a shading style. Extra vertices are inserted so that the UV distortion occurs only at the joint between line segments. There should be no distortion along straight paths, which is preferred for a rectangular selection tool.

Added fixes for gles and addressed bug where line UVs get reverse when winding order is enforced.
