Freestyle: memory consumption optimization in stroke rendering.

Browse Source 
Previously individual strokes were represented by distinct mesh objects
no matter how many vertices and materials each stroke has, although
the vertex and material counts can be quite small depending on the input
scene data.  Now stroke meshes are packed into a minimum number of
mesh objects, so as to reduce the overheads of Blender object creation.
