OK, 1 Giga pixels would be too much for use on a display, but when you
try too render for high resolution devices (i.e. photo typesetting)
you get up to 10k x 10k pixels on a page. And even a usual laser printer
with 300 dpi offers 3k x 4k pixels. That exceeds the limits of the old
Agnus.
Thanks those who wrote the printer.device, it can handle large bitplanes.
Now (with a new graphics.library) we can easily render it using system
code and blitter speed. Unfortunately, I don't think that we can emulate
these capabilities with the older Agnus.
