This patch stitches the vertices along patch edges so that cracks can no longer form when applying subdivision or displacement a mesh. Subpatches are now formed in a way that ensures vertex indices along subpatch edges are equal for adjacent subpatches. A mapping of vertices along patch edges is built to preform stitching. Overall performance is roughly the same, some gains were made in splitting, but some was lost in stitching. This fixes: - T49049 (cracks between patches from material and uv seams) - T49048 (discontinuous normals with true displacement) Reviewers: sergey, brecht Differential Revision: https://developer.blender.org/D3692
