Heights and depths are often rounded somewhat because there are not 
that many distinct values that can be saved in a TFM file. 

Different encoding usually equals different glyphs, and therefore 
different rounding errors. The width usually does not have that problem,
since more values can be saved and characters usually don't change
width when an accent is added.
