: i think we should use a system similar to x.,,...? would this be okay?
Too complicated. I think we should try to keep this a "small"
project. The X Window Font Specification (XWFS?) is too large
as it is. I still think that a filename in a GrLoadFont is probably
the best bet. However, for those wanting font characterstics
(this is only really useful for human font picking, _not_ computer
programs picking fonts), we could either store information
about font size, etc in the font name, like X does, or we could
have a GrQueryFonts that loads them all up, gets their info,
unloads them all, and puts it all up in a (yet non-existent) listbox...

: true - but we could have a devfileio.c which has hooks for fs io
: so os's that support itcan, and those that can't, dont.
: for those that can't we could compile in certain limited files.
That's exactly how we do it now, with the exception of the font loading.
: i'm going to take a look at the xfs andwrite a curt down version
What's xfs?
: to link into the nanox server and microwindows - i will add support
: for bitmapped fonts etc thats allready there...
We should probably stay with the in-core font structure that
supports fixed and proportional fonts. This was designed to keep
core costs down, as most indices are bytes and font width
pixmaps are kept as shorts...

Yes, exactly. That's what GrLoadFont does - request a font.
