Hi,

Here is yet another version that is longer but I think is more correct.
The previous patch fixes a percentage dimension as a percentage of
"font_size".  This works for our case here but might not always be
correct.

This new patch calculate the unknown percentage dimension with the other
known dimension.  It should work the same on our examples (maybe Stephen
you could check that).
