OpenSubdiv/opensubdiv/osd/cpuComputeController.h
Takahito Tejima 8efecb0fca Batching stuffs: generalized kernel batches, table/dispatcher refactoring, multiMeshFactory, drawContext, etc.
2 client APIs are changed.
- VertexBuffer::UpdateData() takes start vertex offset
- ComputeController::Refine() takes FarKernelBatchVector

Also, ComputeContext no longer holds farmesh.
Client can free farmesh after OsdComputeContext is created.
(but still need FarKernelBatchVector to apply subdivision kernels)
