<text> (Or "vector font") A font defined as a set of lines
and curves as opposed to a bitmap font. An outline font
(e.g. PostScript, TrueType, RISC OS) can be scaled to any
size and otherwise transformed more easily than a bitmap font,
and with more attractive results, though this requires a lot
of numerical processing. The result of transforming a
character in an outline font in a particular way is often
saved as a bitmap in a font cache to avoid repeating the
calculations if that character is to be drawn again.
