fme->hennerdrewes: Thanks again for your patch. I had a closer look at the
Writer stuff. Here are some comments:

1. The invalidation of kashidas has to be done per portion. Image this case: The
line starts with one huge Arabic character, the font of which reports a minimum
kashida width of 4000 twips. Then the kashida positions in the line are all
marked as invalid, although the portion which requires the 4000 twips does not
even have a kashida position.

2. I think using a sorted array (or a more 'modern' data structure like
std::set) is more suitable for the kashida array, since right now
IsKashidaInvalid/ClearKashidaInvalid always have to iterate the whole array.

3. if for some mysterious reason if(rSI.MarkKashidaInvalid(aItr.GetStart(),
aItr.GetLength()) fails, we have an infinite loop in itradj.cxx.
