the layout and the font appearance heavily differed on
different browsers and was depending on font size presets.
Most notably NatSkin
was unusable with firefox using an average font size
of 12pt. While 16pt was ok for NatSkin
, konqueror was nearly the same
using 12pt. So now font sizes are not relative to browser presets anymore
(using small, x-small, normal, large, x-large and the like) but initializes
fonts to a pixel value and uses relative values (% or em) to get
different font sizes.
