It now mentions the font name and makes rather more of the smoothing
algorithm and custom glyphs.

produced the <code>MODE 7</code> display on the BBC
Microcomputer. It generates characters from a 5 × 9 pixel
matrix, smoothing diagonal lines to produce an interlaced 10 ×
18 matrix for each character. This font is generated by an
extension of the SAA5050’s smoothing algorithm. In addition to
the characters available from the SAA5050 itself, the font
includes characters from the other chips in the family
(including Cyrillic and Hebrew alphabets) and various other
useful glyphs. All
glyphs are drawn on the same 5 × 9 pixel grid.</p>
18 matrix for each character. Bedstead extends that algorithm to
continuity, converting a 5 × 9 pixel grid into an outline with
smooth diagonals.</p>
<p>Bedstead includes all the character designs from the SAA5050
and its various sister chips, including Cyrillic and Hebrew
alphabets. It also has a large number of custom-designed glyphs,
all of them of course based on the same 5 × 9 pixel grid.</p>

<p>The outline version of the font is generated by an ANSI C program
<p>The standard version of Bedstead is based on a square pixel
grid. This is good for displays with square pixels, but not
entirely faithful to the SAA5050. There is a second version,
Bedstead Extended, that more accurately reflects the character
shapes generated by an SAA5050 driving a 576i display.</p>
<p>The outline version of Bedstead is generated by an ANSI C program
which emits a Spline Font Database file for use with
<a href="http://fontforge.sourceforge.net/">Fontforge</a>, which
can convert it into most reasonable font formats.</p>
