Absolutely.  Using macros can get text to swim around bitmaps to the
left or right.  But I haven't figured out a way to make text swim
between arbitrary bitmaps placed anywhere in the output using just
macros.  Troff has to be taught this.

Actually, you can already do this with ditroff, if your postprocessor
is up to it.  Troff doesn't give a hoot what is inside the \D'x n n ...'
sequence.  It just gets passed on to the postprocessor (except that
all numbers have been converted to typesetter units).  The soon
to be released JetRoff version 2.6 has several enhanced drawing functions,
including filled objects.  Of course, a standard naming convention
would be useful.

Also, line widths should be variable with your postprocessor already.
At a minimum, the current point size should be controlling the line width.

No doubt.  And don't forget (how could you with the CM fonts) that
troff needs to be taught about non-linear scaling of fonts.
