MStatus splitUV::pruneUVs( MIntArray& validUVIndices )
//
// Description:
//
// This method will remove any invalid UVIds from the component list and UVId array.
// The benefit of this is to reduce the amount of extra processing that the node would
// have to perform. It will result in less iterations through the mesh as there are
// less UVs to search for.
