srcBuffer	Input primvar buffer. Must have get_vertex_buffer() returning a gpu::VertBuf buffer object of source data
srcDesc	vertex buffer descriptor for the input buffer
dstBuffer	Output primvar buffer Must have get_vertex_buffer() returning a gpu::VertBuf buffer object of destination data
dstDesc	vertex buffer descriptor for the output buffer
duBuffer	Output buffer derivative wrt u Must have get_vertex_buffer() returning a gpu::VertBuf buffer object of destination data
duDesc	vertex buffer descriptor for the duBuffer
dvBuffer	Output buffer derivative wrt v Must have get_vertex_buffer() returning a gpu::VertBuf buffer object of destination data
dvDesc	vertex buffer descriptor for the dvBuffer
numPatchCoords	number of patchCoords.
patchCoords	array of locations to be evaluated. must have BindVBO() method returning an array of PatchCoord struct in VBO.
patchTable	GLPatchTable or equivalent
instance	cached compiled instance. Clients are supposed to pre-compile an instance of this class and provide to this function. If it's null the kernel still compute by instantiating on-demand kernel although it may cause a performance problem.
deviceContext	not used in the GLXFB evaluator
