Perhaps you mispelled them? They are definitely there, and have
been for a long time.

Well, to pick nits, before PostScript came along, a point was
1/72.27 of an inch. To make things worse, a 24 point font in
X at 75 dpi is 24 pixels high, not 25 pixels high, so apparently
a "point" in X is 1/75th of an inch.
