* mf/feta-alphabet26.mf: Fix a serious bug (design size off by 8pt).
* mf/feta-nummer-code.mf: Reformatted.
(draw_six): Use outline intersection to avoid a self-intersecting
path.
("Numeral comma"): Fix serious outline glitches. This slightly
changes the glyph shape.
("Numeral dash"): Use `draw_rounded_block'.
("Numeral dot"): Use `drawdot'.
("Numeral 1"): Assure identical tangent directions for the
intersection points of paths. The glyph shape improvement is only
visible at very high magnifications.
("Numeral 2"): Use `solve' macro to make the lower right part of
the glyph outline touch the x axis exactly. This changes the
glyph shape.
Minor fixes for better overlap removal support.
("Numeral 4"): Make lefter corner `rounder'.
("Numeral 5"): Assure identical tangent directions for the
intersection points of paths. This improves the glyph shape at
high magnifications.
("Numeral 7"): Use `solve' macro to make the upper right part of
the glyph outline touch the metrics box exactly. This changes the
glyph shape.
Avoid corner in the upper left part of the glyph (causing a minor
shape change).
