Yes, this is a very real problem for things generated in a classic Mac 
environment where the "Times" font was a scalable font, and, of course, 
the Helvetica font, which is a very common Type1/TrueType font and has a 
bitmap font by default in X.

Why scale it at all? If the user asks for 18px, we don't want to stretch 
a 12px bitmap font to 18, and we wouldn't want to show it at 12 either. 
I think the bitmap font matching should be an exact thing only. That's 
why bitmap fonts ship with a variety of pixel sizes to start with. If 
they can't satisfy the rendering, don't use it.

Actually, isn't that exactly how bitmap information embedded into 
True/OpenType is handled?
