david,
that is very interesting material, I think that the chief problem is though
faulty implementation of the CSS spec. by the browser vendors.

It was certainly my understanding that in CSS the font size refered to the
cell and not the Glyph, and this is the definition in Windows. In other
words in a 12pt font the height of the cell should be one sixth of an inch
no matter what system we are playing with. Of course different screen
resolutions will vary the actual size we see.

Frank
