SetDrPt is a macro, found in the file gfxmacros.h.
(its defined as {(w)->LinePtrn = p;(w)->Flags |= FRST_DOT;(w)->linpatcnt=15;}
 but it would be a good thing if you just included gfxmacros.h, rather
 than just define it in your code.  When you include gfxmacros.h you also
 pick up our friends SetOPen, SetWrMsk, and SetAfPt)

I'd upgrade to release V1.2 if I were you.  While the changes between Gamma-1 and
release were not great, there were changes.  one of which might bite you
someday :-(
