I've just found some time to work on this again.  As it is, I have
tried to improve two bits, the setup of the CGContext and
ATSUBreakLine().

I haven't yet found a way to really speed up CGContext setup, even
though it must be immemsely inefficient to do this for every call to
the measuring function and than again for the drawing itself.  I
haven't looked at the CoreGraphics patch yet to see if that would
help, but I really hope it does.

I know that ATSUBreakLine() is slow, because I had a version that
replaced that call and it was considerably faster.  I am working on
that now to recreate some code that I had before (I lost that work
earlier this year).
