Subject: [PATCH] fix(layout): tell an ideographic space typed in the text from
 a fixed-width one
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

python-hwpx reads hp:fwSpace as U+3000, and FormFit measures U+3000 as
the fixed-width space: a quarter of the em that hangs once at a line
end. An ideographic space typed in the text of hp:t is another thing to
Hancom: the glyph U+3000 at the face's advance (a full em in most
faces), which a line may start after, and which hangs at a line end
however many follow each other. The page estimate now passes it to
FormFit as one of its own.

A fixed-width space that starts at or past the margin begins the next
line, even right after a word; FormFit hung it when the word ended
exactly at the margin.

The new fixture holds 30 cells Hancom laid out and saved: rows of
"가나다라마" with one or two typed ideographic spaces, and with
fixed-width spaces, in cells of narrowing widths.
