[XeTeX] resolution (was Re: The future of XeTeX)

[Keith J. Schultz]

Hi William,

You are only partially correct. Yes, you can create very fine structures
off the glyphs. Yet, is only a part of the picture. 

You forget interword spacing and kerning. Gutenberg, could never match
the resolution of microtype. 

Of course, the whole line could be done by hand, but how how exact could one
get? 

regards
	Keith.
