OpenSubdiv/opensubdiv/osd/clComputeController.cpp
Nathan Litke 064115bbe8 Added the CATMARK_QUAD_FACE_VERTEX and CATMARK_TRI_QUAD_FACE_VERTEX kernels. 
* The CATMARK_QUAD_FACE_VERTEX kernel calculates the face-vertex for a quadrilateral face.  It applies to every face after the first subdivision step, and may be applied for the first subdivision step of a quadrilateral coarse mesh.

* The CATMARK_TRI_QUAD_FACE_VERTEX kernel calculates the face-vertex for a triangle or quadrilateral face.  It may be applied for the first subdivision step of a coarse mesh composed of triangles and/or quadrilaterals.

* Both kernels calculate each face-vertex using four vertex indices (triangles are specified by repeating the third index).  Therefore neither kernel uses the F_ITa codex table, and instead the first vertex offset in the F_IT index table is stored in the FarKernelBatch's table offset.
