RE: [CSS3 Text] punctuation-trim

If font designers do not follow conventions, their glyph would be
trimmed out. Thus, CSS should follow JIS and other standards that font
vendors use.

Paul, there's no question about specifying how punctuation glyphs should
be drawn: that's clearly outside the scope of CSS. What's being
discussed
is how the typical placement of punctuation within the glyph box affects
punctuation trimming behavior.
