Like the floating point values it uses, this is another misleading FOG
feature. When writing out a Type 1 font, FOG converts all point values to
integers in a 1000-unit coordinate system. The coordinate system is a good
idea, since ATM expects a 1000-unit em, but as I pointed out earlier, the
integers aren't necessary.
In discussing conversion accuracy, it's worth noting that some TrueType
fonts from significant sources use a 2000-unit em instead of the standard
2048, so they can translate from original FOG data )or otehr Type 1
sources) without any imprecision.
