improvements to the font preview

[Pomax]

It looks like right now the font previewer mixes up the italic/bold instructions,

Also these instructions don't match what CSS does: if an @font-face rule is declared with an explicit font-style or font-weight then the bound resource for that rule will only be used there. Rather than using the font "in faux italic" or "in faux bold" mode, instead CSS will apply "the font you indicated" whenever it sees italic or bold, so this:

@font-face {
  font-family: myfont;
  src: url("myfont-regular.woff") format("WOFF");
  font-weight: bold;
}

paired with this:

<p style="font-family: myfont; font-weight:bold">This is bold</p>

will not style as bold text at all. It will instead go "I see tuple {family:myfont, weight:bold} and I have been told that this means I need to use the resource myfont-regular.woff to style that", and then it does. This paragraph will be regular text.

Additionally, the font previewer does not put the format("...") indicator in the CSS for loading the font, which can lead to a font not actually being loaded.
