Any use for glyph bounding boxes in printer driver?

[Ian Pilcher]

Currently, the Wine PostScript driver stores the bounding box (xMin,
yMin, xMax, yMax) for every glyph in every font.  This information is
not currently used, and I'd like to get rid of it.  (Note: this is
distinct from the advance width of each glyph, which is certainly
required.)

Since I'm not that familiar with either, however, I figure I should try
to confirm that this is indeed the case.

So, does anyone know of any API that an application or the GDI can use
to get the dimensions of an individual glyph from a "real" Windows
printer driver?  (I have verified that calling the GetTextExtentPoint
functions with a one-character string returns the height of the font,
not the height of the glyph.  For example, it returns the same height
for 'A' and '_'.)

Thanks!

What about GetCharABCWidth* what does this function use? (or could it use
this?)  I see the function still shows a fixme (or atleast the last time I
checked).
