In Gecko, that's just happenstance, since that's what Mozilla's values
turn out to be at default default settings, meaning a DPI of 96, and
font size of 16px. Note that's px, not pt. Gecko does not use pt for
prefs. (Points are functionally crippled for screen media.) The sizes
Gecko uses are px. For the smaller sizes, Gecko has a table of values
you can see at
http://lxr.mozilla.org/seamonkey/source/content/html/style/src/nsStyleUtil.cpp#115
and following, with the index to keywords on line 144. For the larger
sizes, there is a scale rather than a table at line 197.
http://members.ij.net/mrmazda/auth/absolute-sizes-M.html has my full
tabulation of mozilla behavior. Mozilla
http://bugzilla.mozilla.org/show_bug.cgi?id=187256 has my proposal to
improve behavior of these sizes that would break it apart from other
browsers and the spec. I am formulating a conforming CSS3 proposal.
