Allegro v2.2 can apply gouraud (linear gradient) shading to polygons-
the docs don't mention anything about more sophisticated shading.  Find
POLYTYPE_GCOL, POLYTYPE_GRGB, POLYTYPE_ATEX_LIT and POLYTYPE_PTEX_LIT in
the Graphics section of the documentation.  The POLYTYPE definitions can
be used in conjunction with most of the polygon rendering functions.
