Excuse me, but I think that this represents a serious mind
set problem. There is absolutely nothing "bogus" about
the fact that some characters and their ligatures may
extend above/below other characters.
The bogus factor is the mind set that AbiWord was created
with in that all characters are a fixed width, and as a
result you end up with very bad clipping when text is
highlighted and things are not always properly re-drawn
because the engine doesn't have enough information to
properly redraw.
Each character (at a minimum) should have a metric
associated with it that indicates 1) A base width which
can be used for highlighting 2) An extention before and
after this base width which is used to properly re-draw
characters which might be affected by any draw operations.
