We currently shrink Sans and Serif fonts to 90% for experimental Condensed fonts. The OpenType specifies several usWidthClass (see http://www.microsoft.com/typography/otspec/os2.htm#wdc ) of which Condensed (3) is 75% aspect ratio of Normal (5) and Semi-condensed (4) is 87.5%, i.e. closest to 90%, aspect ratio of Normal. To follow the naming of the OT specs our current 90% Condensed should be renamed Semi-condensed. This might be unnecessary or even negative for users currently using it, even if experimental. However the earlier the better. The current usWidthClass is 5 which is Normal. For a Condensed font it should be 3 and for a Semi-condensed it should be 4. This must be fixed. NameID=16 could be set so smart applications can put DejaVu Condensed in the same family as DejaVu fonts but that's another bug.
