	My experience with ATM 2.0 agrees with M. Costello. When I got
ATM I followed the directions and only installed the 12 point bitmap fonts.
Where ATM actually seems to fall down at smaller point sizes is in the
character spacing. My attempts at generating 10 point sizes were ghastly.
	It occurs to me however, that I have tried neither using my
Imagewriter (I was editing a document and never printed it), nor did I
try using fractional widths (which isn't supposed to work with the IW
anyway).
