 I was looking through the PDB for a good procedure to return the

Isn't the first what you want, anyway? I can only guess that the real
problem is that gimp-text clips away part of the bounding box. Try using
-1 as border size, this should leave the standard ascent and descent space
around the charatcers, allowing you to align everything correctly.

RE: New text metric procedure

[Nick Marden]

Oh, something I noticed from using my new procedure: The string
metrics returned by gdk_string_extents() aren't always exactly the
same as the metrics of the bounding box returned from gimp-text.
Apparently gimp-text uses something like gdk_string_extents, but not
exactly the same.

So far all I have seen is an occasional small height difference, which
is easy to correct for progamatically, by comparing the height
returned from text-get-string-extents with the height of the floating
selection created by gimp-text, and translating the layer accordingly.

Of course, that's far from elegant, so I'll get off my butt this
weekend and look into why the numbers don't quite jive.
