When the key of a font property is @c Msize or @c Mresolution, its
value is an integer. Otherwise the value is a symbol.
- "The font property that belongs to font F and whose key is @c
- Mxxx" may be shortened to "the xxx property of F".
+ The notation "xxx property of F" means the font property that
+ belongs to font F and whose key is @c Mxxx.
The value of a foundry property is a symbol representing font
foundry information, e.g. adobe, misc, etc.
