A little more followup. The gtk() device uses gdk_string_width to find the character extents. That seems undocumented anywhere in the gtk+ sources. It is returning the maximal descent for the font for all input strings on my system. Looking at the current gtk+-1.2.7 sources it appears to call XTextExtents, and that _should_ give the string descent. Since gdk fonts are private opaque structures
