   8 # Every call to PixelType defines one new GP_PixelType, order defines
   9 # the numbering. Undefined type is defined automatically.
  10 # No other functionality than PixelType() should be defined here.

  12 # This file is sourced by all the generating scripts.
  13 # Moreover, the generated files are sourced by almost all Gfxprim sources,
  14 # a complete recompilation is required after any change.
