I assume that is with some contemporary pixel size r. Unless you use
some good compression technique, performance will be proportional to
r^{-2}. With some good textual image compression systems (PNG, G4FAX,
JBIG, etc.) used on the bitmaps, performance might become proportional
to around r^{-1.3}. Pixel sizes for color CRTs have stabilized now at
around 0.22-0.25 mm, as smaller aperture masks are not feasible. But who
knows what's coming next? Pixel sizes down to 0.05-0.10 mm, as we have
already with laser printers, would certainly be desireable for e-book
applications, etc.
