   7 # Run ./pngstest on the PNG files in $srcdir/contrib/testpngs which have the

  10 #  gamma: one of; linear, 1.8, sRGB, none.
  11 #  alpha: one of; opaque, tRNS, alpha, none.  'none' is equivalent to !alpha

  13 # NOTE: the temporary files pngstest generates have the base name gamma-alpha to
  14 # avoid issues with make -j
