This generates the font and the html test file in one go, so that we
can be assured of using the same set of glyphs in both. This also adds
the template file used to generate the SVG font.
Other tweaks:
- Adds additional parameters (include, exclude) to file selection. This
was useful when debugging. Other parameter tweaks as well.
- Changes format of html file to flow text, show information on hover.
This is better than the old table layout.
- Changes transform of SVG to put it at top of ascent, rather than top of
EM square. Text selection uses ascent+descent, and the SVG was higher
than the selection.
- Adds a little more status output controlled by the verbosity flag.
- Quiets the ttx output on reading/writing, also controlled by verbosity.
