The evdev driver does not allow to set a custom axes rotation
as the mousedrv driver does with the option "AngleOffset".
This option is necessary for some trackballs, for example the
Logitech Cordless Optical TrackMan which has the optical
sensor off-axes (in MS Windows, the Logitech proprietary driver
adjusts the offset).
X.Org Bug 27688<http://bugs.freedesktop.org/show_bug.cgi?id=27688>

this patch seems simple enough that we could add it to the server as a
standard property for pointer devices, isn't it? I'd much prefer that so we
don't have to re-implement it for the various drivers.
But isn't it already in the server?
Since 1.9 and commit "dix: add 3x3 transformation matrix xinput property
for multi-head handling", we already have a property
"Coordinate Transformation Matrix" that can handle arbitrary
transformation matrix. And a rotation can be seen as a matrix, no???
It's clear that a matrix is not very easy to handle by human people, but
we just need a tool that provide it.... ;)
Cheers,
Benjamin
