Thanks. Unfortunately I think I asked an x-y question. What I really want to 
know is the width of the glyph and I thought I can just multiply the height 
factor to the original width of the glyph. It seems not to be the case. The 
multiplied result doesn’t match with the width on glass. More precisely :height 
* glyph width != posn of point after - posn of point. Is this expected?

Also I can’t use posn for calculation since sometimes the text might not be on 
screen.
