stored render prog vertexMask is initialized with cellCgbGetVertexConfiguration().

Even though VERTEX_MASK_XYZ_SHORT and VERTEX_MASK_ST_SHORT are not real attributes,

they come before the VERTEX_MASK_MORPH to reduce the range of vertex program

permutations defined by the vertexMask_t bits on the Xbox 360 (see MAX_VERTEX_DECLARATIONS).
