- If $KEY is @c Mfamily, @c Mweight, @c Mstyle, @c Mstretch, @c
- Madstyle, or @c Mregistry, this function returns the
- corresponding value as a symbol. If the font does not have $KEY
- property, it returns @c Mnil.
- If $KEY is @c Msize or @c Mresolution, this function returns the
- corresponding value as an integer. If the font does not have $KEY
- property, it returns 0.
+ If $FONT is a return value of mfont_find (), $KEY can also be one
+ of the following symbols:
+
+ @b Mfont_ascent, @b Mfont_descent, #Mmax_advance.
