Set mouse pointer resolution a.k.a sensitivity interactively?

[Simon Thum]

Hi Peter,

the third column is for offsets, you should only ever use these with 
absolute coordinates/devices so that's fine. Scaling, shearing and 
rotation should be possible with the first two columns, and those also 
make (some) sense for relative devices.

Cheers,

Simon
