The problem with allowing "fallback to a font family that has real
italics" is that it doesn't work for scripts that typically lack
italics (e.g. Japanese).

For faux bold I think we should define it as representing a 700 weight
font which exists if and only if no weight greater than 500 exists for
a given family.  Combined with weight mapping rules, that will fit
with existing platform API usage (e.g. GDI).
