In the spirit of equal-opportunity advertisements, I must mention that there
are a set of extensions to the original TrueType format called Apple
Advanced Typography, which have been around for several years. They were
originally used by QuickDraw GX, and are now used by Apple's Unicode imaging
solution, ATSUI (Apple Type Services for Unicode Imaging). ATSUI has been
part of Mac OS since version 8.5, and is also part of Apple's Carbon API.
