I want to define an opaque font that exactly overlaps the current
screen's font.

I can use (font) [ which returns ("9x15" 9 15) ] to get the current
screens font, and then use these numbers to define the opaque font's
name, width and height.

But I can't see anywhere which will give me the OFFSET argument I need
to make the opaque font exactly overlap the current font (i.e. 4 pixels
or 26% for the "9x15" font).

Does anyone know a way of retrieving the baseline offset of a font ?
