Font Religion (was: How can I check for the existence of a glyph inTeX?)

TeX understands type 3 fonts (provided they have a TFM) and my drivers
(dvips and TeXview) understand type 3 fonts, so dismissing them as not
useful isn't just harsh, it's factually incorrect. In fact, with
appropriate configuration of bitmaps, even PCs and Macs can use them.

Under your definition most Macintosh NFNT resources are `wrong' -- in
fact the whole Macintosh way of doing things is wrong.

Your philosophy is not that of TeX though, nor is it the philosophy all
operating systems TeX runs on (e.g. MacOS).
