I think it's something like the height of a representative (uppercase, full
staff, no over/underhang) character obtained via GetTextExtentPoint -- with
the current WM_GETFONT selected into the HDC, and
2*GetSystemMetrics(SM_CYFIXEDFRAME) and 1*GetSystemMetrics(SM_CYEDGE) added
to it. Of course, XP themes or an ownerdraw style will no doubt complicate
things.
