* replace void* of all kernel applications with CONTEXT template parameter. It eliminates many static_casts from void* for both far and osd classes. * move the big switch-cases of far default kernel launches out of Refine so that osd controllers can arbitrary mix default kernels and custom kernels. * change FarKernelBatch::kernelType from enum to int, clients can add custom kernel types. * remove a back-pointer to farmesh from subdivision table. * untemplate all subdivision table classes and template their compute methods instead. Those methods take a typed vertex storage. * remove an unused argument FarMesh from the constructor of subdivision table factories.
