[PATCH] improved mouse pointer acceleration

[Simon Thum]

Hi everyone!

I have recently updated my patch to improve the mouse pointer 
acceleration in X.org. As always, I invite anyone interested to try it 
and give me some feedback on it, especially if you have unusual pointing 
devices.

The main point of the patch is you can use different pointing devices 
and adjust them individually, which is important for laptop users. Also 
the pointer acceleration becomes much more predictable, which results in 
increased usability.

It is also suitable to tame high-precision mice, which seems to be a 
growing need given the fact a patch for this single problem has been 
developed independently.

I'm now quite content with the patch and have tested it using two 
simultaneous devices with vastly different precision (crappy mouse vs. 
synaptics touchpad with native resolution). In about half a year, 
stability was never an issue.

The patch and documentation is in Bugzilla #8583:

@Daniel: Since you took the bug, can I assume you are going to apply 
along hotplug (if approriate)?
