Summary: Curve ORCO was not calculating properly for cyclic 2D curves. - Needed to split vertices for blender internal renderer. Otherwise it's not possible to map last face to a proper texture location. - Needed to tweak curve->mesh conversion to respect cyclic flag along U direction. - Removed check for orcodm in curve.c:add_orco_dm since this code is only called if there're enabled constructive modifiers on the curve.
