OK, so I've chosen this really cool OUTLINE font that I want to scale to say,
32 points.  I compute the necessary character cell dimensions, call
GpiSetCharBox() and GpiSetCharSet() to select my new logical font.

QUESTION: How do I get the metrics for this font AT THE SELECTED POINT SIZE?
Calling GpiQueryFontMetrics() at this point returns the same metrics structure
I got back from my initial font query, with metrics designed around a 12 point
font or so.

My only current idea is to compute the ratio of logical.lMaxBaselineExt to
physical(base).lMaxBaselineExt and multiply the metrics by this ratio to
scale them (ascent, descent, maxwidth) to the point size I'm using.  This
seems bogus and prone to round-off error.

Am I missing something?

Thanks.
