Two parallel projects that got incompletely merged.

The boxfill() routine was added as part of Ule Gruenebaum's
work to allow solid-fill and pattern-fill boxes in the existing
plot styles.

The filled_polygon() routine was part of Petr Mikulik's large
PM3D code block that does 3D surface-plots and allows
color-mapping a Z-range to a color palette.

Both of these code blocks were marked as EXPERIMENTAL
during much of the version 3.8 development, and were worked
on by different people.  In retrospect they probably should have
been merged earlier, but they weren't.  If nobody else tackles
the job, I'll probably do it as part of general code cleanup 
eventually.

This sort of thing can happen in particular because new
features tend to get implemented first for a restricted set
of terminal drivers. It is only when they are later expanded
to a more complete set, or get abstracted to a higher layer
of the code, that they collide.
