Well, I'm actually a little confused about font/point/pixel sizes.  When I 
talk about font size it's in points: MetaNormalLF Roman 11.5 points.  
(Apparently fractional point sizes are pretty common in the print industry.)

I'm not entirely sure how the pixel size is used.  At first I was thinking 
that it was points per EM, but I'm really confused after reading the last 
paragraph in the 'note' for FT_Set_Pixel_Sizes.  8x8 cell??? You're 
definitely not talking about ppem.

Also, I didn't think fractional pixel sizes were possible?

That would be very nice.
