Hi!

I've improved the Font Plugin. In the previous version, the font size
could only be specified in pixels. I've made it possible to specify it
in any of the ways, in which font sizes can be specified by the "font-
size" CSS style. See here:

https://www.w3.org/TR/CSS2/fonts.html#propdef-font-size

Now you can say "{FONT(size=125%)}...{FONT}" or
"{FONT(size=1.5em)}...{FONT}" or ...

The changes were small. However, I've removed the "filter" property
from the "size" argument. I don't understand the implications of this
fully yet.

I think the improved version should go into Tiki.  :-)  I'll update the
documentation.

The new version is attached.

Cheers,
Volker
