Glyphs and the text system

Hi,

I'm currently working on rewriting NSLayoutManager as a part of fixing
the text system. Basic glyph handling is done, and the new
implementation is completely glyph based, which brings up a few
questions:

1.
Glyph generation. This needs to be done in the backend. I'll write one
for the freetype-based code in back-art, but other backends might be a
problem. I can write a dumb default one that works like the current one,
though.

2.
To display I'll use GSShowGlyphs(), so this will need to be implemented
as well. I'm not sure about how this affects printing.

3.
In NSFont.h we have:

typedef unsigned int NSGlyph;

Is this intentional? How many bits is it supposed to be?
