- changed Far::PatchDescriptor size for GREGORY_TRIANGLE to 18
- modified Far::LoopPatchBuilder to construct full quartic Gregory patch
- fixed Far::LoopPatchBuilder bug related to face points near boundaries
- updated Far patch basis evaluation for Gregory and Bezier triangles
- updated Osd patch basis evaluation to match Far
- updated Osd GLSL patch size for Gregory triangle to 18
- modified Osd GLSL Gregory triangle eval and tess settings for quartic
