The font size value not known before actually starting the rendering,
but the document is created before that. Think about this: You create
a document in Windows and render in Linux. Will it work if you
dependended on measures from fonts from Windows which are not present
in Linux?

That seams interresting, but for which font would that refer to? One
can have multiple fonts in the same drawing, theorically. Or should we
restrict to only one font?
