          Priority: low
            Bug ID: 73700
          Assignee: dejavu-bugs at lists.freedesktop.org
           Summary: Meta-bug: Missing a tag for font information (i.e.
                    general bugzilla tag guideline)
          Severity: enhancement
    Classification: Unclassified
                OS: All
          Reporter: Ulrich.Windl at rz.uni-regensburg.de
          Hardware: All
            Status: NEW
           Version: unspecified
         Component: General
           Product: DejaVu

My apologies if this is the wrong product or component, but I noticed this:
Bug descriptions (seem to) use "[kerning]" for kerning problems (horizontal
alignment most of the time) and "[hinting]" for pixel placement for small
sizes.

I'm missing one thing that is related, but neither [kerning], nor [hinting]
(IMHO): [metadata] or [fontinfo]

Why? I had a problem with LibreOffice (and OpenOffice) with dual page alignment
("Registerhaltigkeit" in German, I'm missing the correct english phrase): When
I changed one word in a paragraph from normal to italic, line spacing
"exploded" (i.e. LibreOffice added extra blank lines above or below the italic
word)

Needless to say that first, you don't want that, and second professional fonts
don't have it

My guess is that the different "cuts" of the font use sligtly different font
information for ascenders and descenders (or maybe even worse: the ascenders
and descenders actually differ in the glyphs)

So if you have one font family (as Deja Vu is expected to be), the font info
should be adjusted for a true family look, also.
