I don't know how to "compress" glyphs, actually.  I hoped that we can
get away with just "padding", which boils down to enlarging their
width metrics.  But if we need to make the width significantly smaller
than the font glyph font says, I don't know what would be the effect
of that, and I have no idea how to "shrink" a glyph on display.
