Returns a font description combining the attributes of a given font description with a set of font attributes.
The 
augment-font-description
 function returns a font description that contains all the attributes of 
fdesc
 combined with the extra 
font-attribute
s. The 
:stock
 attribute is handled specially: it is omitted from 
return
, unless it is the only attribute specified.
If an attribute appears in both fdesc and a font-attribute , the value in the font-attribute is used. The contents of fdesc are not modified.
