FontDescription.setFamilyStatic

Sets the family name field of a font description, without copying the string.

This is like [pango.font_description.FontDescription.setFamily], except that no copy of family is made. The caller must make sure that the string passed in stays around until desc has been freed or the name is set again. This function can be used if family is a static string such as a C string literal, or if desc is only needed temporarily.
