p.s. Re: getObjectExtent() question

I think the 2nd paragraph of the gOE description reinforces my guess at the 
intent of the sentence in question:

[[[
The contribution of text elements to the object extent is conceptually 
calculated from the containing parallellogram of the displayed text, 
defined as follows. The length of the side in the text-up direction is the 
bottomline-to-topline distance of the font, after computation of the 
effective font size that reflects all text attributes, the height of the 
Restricted Text box, the Restricted Text Type, and the Style Properties 
text-size and text-font. The length of the side in the text-baseline 
direction is the length of the restricted text box if the entire Restricted 
Text element is contained within the object, or the sum of the glyph widths 
if only an Append Text element is within the object.
