These continues proportional-width glyph encoding.

unclear about which units accept floats/integers, which leads me to
assume that it handles either and rounds as appropriate.

in mdoc_term.c and man_term.c down into term.c. This is still not
implemented in term.c, although stubs for width calculations are in
place. From now on, offset, rmargin, and other layout variables are
abstract screen widths. They will resolve to the the familiar values
for -Tascii but -Tps will eventually use points instead of chars.

TERMFONT_BOLD (Courier-Bold) and TERMFONT_UNDER (Courier-Oblique). It
doesn't look half bad. This accomplished through tricksy juggling of
the one-char back-buffer.

This paves the way for closing/reopening scope in the event that a font
changes.

simple state machine. This paves the way for decorated text.

apparently doesn't collapse in PostScript (surprise!). Makes output
files much more compact.

output. This is more tricky than you may think: we can't just call the
header function out-of-state (i.e., before a flushln has occured)
because we'd clobber our current state. Thus, we call at the beginning
and dump the output into an auxiliary buffer.
For the record, I don't think there's any other clean way to do this.
The only other Way That Works is to copy-aside *all* termp state, zero
it, and do the necessary headf/footf. This is just as complex, as
memory needs to be alloc'd and free'd per margin.
Unfortunately, this prohibits page numbering (the margin is only printed
once), so I'll probably end up re-writing this down the line.

Made low-level engine functions into function pointers.

terminal_free() in favour of ps_free() and ascii_free(). Moved ps_*()
functions into term_ps.c so that they don't clutter up term.c.
