Hi,
The font descent is the maximum descent for all characters in that
font, so it will not help me to position the character correct.

To clarify this and my original question: It is easy to find
infomation about how to get a fonts ascent and descent, but I cant
find any info about getting ascent/descent fot individual glyphs.
I'm not sure if this is correct, but looking at this:
http://developer.apple.com/documentation/Cocoa/Conceptual/FontHandling/Tasks/GettingFontMetrics.html
... seems to indicate that performing the correct rectangle math
using the font's -lineHeight, -ascender, and -descender methods
combined with the bounding rect of the glyph should give you a
remainder rectangle whose height is your answer.
