please test this patch.

You are beautiful!
I am worried about the performance implication of creating and removing layouts
every time we measure a string but it is a good starting point.  I'll have a
more detailed analysis in a day or two.

Ok, now that 1.1.7 is out I'll have a look at this.  It works nicely out of the
box and you appear to have hit the major points.  However, I'll need to do some
performance tests.

I'm looking at the patch now.

gnumeric pango patch

this patch was changed. and checked that 1.1.7 operated.

Patch applied.  I adjusted the approach slightly but left most of it as is.
The next question is whether we should be doing the line splitting ourselves or
letting pango handle it.  Eventually I'd like to more towards doing a per
visible cell layout so that we can cache more.

The only regression I see with the patch is that it does not handle reverse
video for the autocomplete text.

Lets close this one and open new bugs the resulting breakage.
