I've tried to implement this thing, though I am not convinced that it is
a minor inconvenience.
Getting the ascent/descent of one font is no problem using
gimp_text_get_extents. Getting the information if a given string has
a ascent or descent _is_.
I see three solutions:
- "knowing" which letters have a descent|ascent. Bad if you have dif-
ferent types of fonts. More important still this knowledge is ex-
ternal.
- using bitfiddling to see if there is a ascent or descent.
- letting the gimp_text_get_extents return two additional fields,
namely ($has_ascent,$has_descent).
I favour the last ;)
