- Made OpenSubdiv_GLMesh private Previously, it was still accessible via C-API from C++ code. - Don't implicitly refine evaluator when updating coarse positions, now there is an explicit call to do this. Allows to first apply all changes to the coarse mesh and then refine once. - Added coarse positions update from a continuous buffer with given starts offset and stride. Allows to update coarse positions directly from MVert array. - Refiner is no longer freed when CPU evaluator is created. Allows to re-use refiner for multiple purposes.
