The initial values for maxasc and maxdes (renamed from maxdesc) is obtained as a maximum of max ascents/descents of all row elements. This allows to get rid of Paragraph::highestFontInRange and FontList::highestInRange. Some auxilliary variables declarations are also moved to where they are needed.

I don't think it's worth the effort to implement a more effective
|
|
datastructure, because the number of different fonts in a paragraph
|
|
is limited. (Asger)

Nevertheless, I decided to store fontlist_ using a sorted vector:
|
|
fontlist_ = { {pos_1,font_1} , {pos_2,font_2} , ... } where
|
|
pos_1 < pos_2 < ..., font_{i-1} != font_i for all i,
|
|
and font_i covers the chars in positions pos_{i-1}+1,...,pos_i
|
|
(font_1 covers the chars 0,...,pos_1) (Dekel)
