|
* Calling Text::getFont is slow. While rebreaking we scan a
|
|
* paragraph from left to right calling getFont for every char. This
|
|
* simple class address this problem by hidding an optimization trick
|
|
* (not mine btw -AB): the font is reused in the whole font span. The
|
|
* class handles transparently the "hidden" (not part of the fontlist)
|
|
* label font (as getFont does).
