When loading OpenType fonts, either as a replacement for the standard
14 fonts or an embedded one, we previously passed the font size as the
_point_ size to the loader class. The difference is quite subtle, being
that Gfx::ScaledFont uses the optional dpi parameter to convert the
input from inches to pixels.
This meant that our glyphs were exactly 1.333% too large, causing them
to overlap in places.
