[mpeg-OTspec] Toward a Composite Font format specification

[Daniel Strebe]

Thomas,

Thanks for chiming in. To clarify, do you mean to advocate scaling horizontally within the same design space when you mention faux small caps? (Meaning, without increasing the glyph advance width, escapement, and kerning values?)

I'd advocate keeping the three different scaling factors (overall, X
and Y). I can honestly imagine plenty of use cases for them, both in
traditional and non-traditional cases.

One use for asymmetric X/Y scaling is in manufacturing small caps. One
could use a composite font mechanism to build faux small caps,
possibly scaled slightly so as to be slightly wider than strictly
proportional scaling. Ditto for creating numeric (or alphabetic)
inferiors or superiors. Using the composite font mechanism would allow
for taking the base glyphs from a heavier weight of the "same"
typeface....

cheers,

T
