  75.      projective texture effects will be processed on a per-vertex basis
  76.      instead of a per-pixel basis, unless the the texture matrix is set up to
  77.      be projective.  (A projective texture matrix is defined to be one in
  78.      which any of the 13th, 14th or 15th elements is non-zero.)  In addition,
  79.      if either two-sided lighting or fragment lighting is in effect,
  80.      projective texture effects will always be processed on a per-vertex
