>>ASSERTION Good A
xname returns the ink and logical extents of each character in addition 
to the overall extents of a string.
>>STRATEGY
For every Locale specified by the user in the configuration file, create
each of the base font sets specified by the user, by calling
XCreateFontSet, then call XmbTextPerCharExtents to get the extents per
character and the overall extents.  Check to make sure the extents are
valid. Also make sure the overall extents are equal to the combined
extents of the characters.  Make sure the returned status is good.
