Hints aren't designed to be used on the virtual page, they are designed
to be used on the physical page.

What that gibberish means is that hints that are used for 6pt letters
on a 300dpi printer would be equivalently used on 3pt letters on a 600dpi
printer.  The hints work with machine pixels, not point sizes.

Needless to say, 2540dpi printers don't need many hints, eh?
