  36  * Note: The first 32 attributes match the VERT_ATTRIB_* definitions.
  37  * However, we have extra attributes for storing per-vertex glMaterial
  38  * values.  The material attributes get shifted into the generic positions
  39  * at draw time.
  40  *
  41  * One reason we can't alias materials and generics here is display lists.
  42  * A display list might contain both generic attributes and material
  43  * attributes which are selected at draw time depending on whether we're
  44  * using fixed function or a shader.  <sigh>
