i'm looking for some code to shrink the bounding box to just what it needs to be for the entered text.

for example, i draw an mtext object with a width of 10, and a height of 10, and only one letter in it.
whn i run my code, and select the objects, i want the bounding box to be the width of the 1 letter (and height), (plus the normal offset, that doesn't concern me)

i've got code that makes a selection set, and limits selection to mtext objects.
i just need to know how to force the bounding box height, width
