OpenSubdiv: Corrections to GLSL version

Was own mistake in the last minute fixes, now matcaps should
work just fine.

Fix buffer overrun lofting nurbs

Fix own mistake in curve refactor

OpenSubdiv: More proper loop for UV map evaluation on CPU

This is just updating code from our side, actual evaluation is still
disabled because it doesn't support face farying data evaluation.

OpenSubdiv: Fix crash caused by applying subsurf on non-mesh object

OpenSubdiv: Correction to vert edge/face orientation code

non-manifold case didn't start ordering from the correct edge.

OpenSubdiv: Switch CPU evaluator to use uniform refinement

This way the result matches GPU viewport and becomes really close to out
legacy subsurf code.

OpenSubdiv: Mark non-manifold verts as sharp

OpenSubdiv: Disable topology check happening from OpenSubdiv side

This check doesn't handle multiple non-manifolds cases which is rather
really annoying currently.

OpenSubdiv: Work on better vert edge/face orientation code

Previous version of code didn't handle cases like hourglass connectivity
with loose edge. The new code is supposed to handle all this cases.

Fix T45620: Coplanar faces w/ flipped normals not selected

Cleanup: remove redundant normalize

Fix bgl so that get-methods that take a string use strings instead of bgl buffer objects again

Add bool parser for PyArg_ParseTuple

Use for mathutils.bvhtree

Fix T45625: Unpredictable grid fill

Detect when there are < 3 corners & automatically calculating the span isn't useful.

Fix grid-fill offset option

Wasn't applied relative to the active vertex.

Fix T45644: bpy.utils.smpte_from_frame drops frame

D1444 by @lichtwerk, with minor fix & docstring updates

Fix T45649: Adding Point Density Texture to World Color Crashes Blender.

Crash was caused by missing field in NodeShaderTexPointDensity.

Committed with @dingto blessings.

Use auto-offset after adding node from search menu as well
