Implemented EvalPatchesVarying and EvalPatchesFaceVarying methods for Osd::*Evaluator classes, i.e. cpu, omp, tbb, GLXFB, GLSLCompute, OpenCL, and CUDA. Also, the GPU Kernel implementations have been updated to use the common patchBasis implementation instead of re-implementing methods to compute patch basis weights locally.
