Well, supporting .GS mainly means proper handling of vertical spacing
and that its parameter (either L, R, or C) is parsed to adjust the
horizontal position of the gremlin image.  Without those macros, the
image is inserted as-is.

The `.st' command is emitted by grn itself; due to lack of knowledge I
haven't changed this -- all troff variants I know of don't have this
primitive.  Do you know what .st (and its friend .sc) will do, and
which troff version it comes from?
