	The code was trying to make winding consistent and manifold, same as OpenSubdiv expects it to. Unfortunately, the code was having some issues in corner cases so the winding wasn't really correct. Fortunately, the latter (compared to when this code was originally written) supports orientation on OpenSubdiv side. Removing code which is currently unused in Blender and which had known issues. Is simple enough to bring the code from Git history if the functionality is needed in the future.
2019-04-17	ClangFormat: apply to source, most of intern	Campbell Barton
	Apply clang format as proposed in T53211. For details on usage and instructions for migrating branches without conflicts, see: https://wiki.blender.org/wiki/Tools/ClangFormat

	Replaces direct access to std.
2018-07-16	OpenSubdiv: Re-work C-API integration	Sergey Sharybin
	Main goal is to make API simpler to follow (at least ion terms what is defined/declared where, as opposite of handful big headers which includes all the declarations), and also avoid a big set of long and obscure functions. Now C-API files are split into smaller ones, following OpenSubdiv behavior more closely, and also function pointers in structures used a lot more, which shortens functions names, UV integration part in GL Mesh is mainly stripped away, it needs to be done differently. On a related topic, UV coordinates API in converter needs to be removed as well, we do not need coordinates, only island connectivity information there. Additional changes: - Varying interpolation in evaluator API are temporarily disabled, need to extend API somewhere (probably, evaluator's API) to inform layout information of vertex data (whether it contains varying data, width, stride and such). - Evaluator now can interpolate face-varying data. Only works for adaptive refiner, since some issues in OpenSubdiv itself. Planned changes: - Remove uv coordinates from TopologyConverter. - Support evaluation of patches (as opposite to individual coordinates as it happens currently). - Support more flexible layout of varying and face-varying data. It is stupid to assume varying is 3 floats and face-varying 2 floats. - Support of second order derivatives. - Everything else what i'm missing in this list.
