- I don't have any particular inside info on this issue, but it seems more
- likely that the special requirements of Corel -- in particular, the ability
- to take a rendered glyph and allow the user to manipulate the individual
- primitive elements which are used to produce it -- would require a special
- engine for *any* font technology.
-
- Normally, if you want to use the character "A" on a computer, your program
- needs only to manipulate the single ASCII byte 0x41. In a WYSIWIG system,
- you also need to know the vertical and horizontal extent of the rendered
- glyph, but that's all: you send the ASCII character to the output device
- without any interest in the number or characteristics of the lines and
- curves which are used to construct the glyph.
-
- In Corel, however, you have the ability to manipulate the rendered glyphs
- as graphic elements, so there are special requirements placed on the
- interface to any scalable fonts...and thus the need for a special driver.
-
- The same comments would apply to Adobe's TypeAlign program as it uses
- PostScript T1 fonts.

- Comments?
