[Fontconfig] Select by name + properties (italic/width)?

[mathog]

This does raise a question though.  If a document is prepared on a 
system that has, for instance, "Arial condensed",
and it must be handled on a system which just has "Arial" (and for 
argument's sake, no other condensed fonts)
how does one deal with the situation?  Is there a way to convince 
FreeType to expand/contract the Arial font that
it does have?  Does FontConfig have anything to do with this process?

I know there is: FT_Set_Char_Size() which has separate char width and 
height fields.  If the width/height were
changed from 0/height  to (some fraction of the height)/height, would 
this accomplish the desired effect?

Thank you,
