Comment 4 for bug 168164

Marked a couple dupes of this bug, see left column. There is some good discussion at those bugs, but this one seemed to be the most to-the-point. Here's a quick recap:

The font sizes in Inkscape are not "pt" but "px"! Go to the source of your
svg file and change font-size from "11px" to "11pt" and look what happens
when opening the file in Inkscape again: font size is 13.75 (px) now

90 px/in = 1.25 px/pt
72 px/in = 1.00 px/pt

To which Gez replied:
That is so wrong. Points is a standard unit for type. Every program uses points so using pixels (which is tied to the resolution) is imo the worst choice.

Mercury then suggested 2 options:
1. In Text tool panel add a unit combobox - "px, pt, mm, etc".
2. Somewhere in preferences add type units (like in Photoshop) - well, everybody knows what 12th font is, but no one knows what is 2mm font is.
