Hardware-based screen magnification

[Samuel Thibault <sthibault debian org>]

Hello,

Now that xrandr 1.3 has panning support again, I have written a small
documentation on how this can be used for simple hardware-based screen
magnification:

the advantage over compiz-based magnification being that it's completely
hardware-driven (except the mouse tracking), thus CPU-free and smooth.

Concerning Orca, that could be an option that users might prefer on
sluggish machines. Concerning Gnome, the shortcut to cycle modes might
be a useful addition. Integrating panning configuration in a nice gui
tool would probably be useful too.
