xfree86: init pointer feedback controls from options

Browse Source 
With InputClass support, it makes more sense to cover all
aspects of acceleration in options. Previously, one could only set the
default on the command line.

Set numerator and denominator of the acceleration factor. The acceleration
factor is a rational which, together with threshold, can be used to tweak
profiles to suit the users needs. The
.B simple
and
.B limited
profiles use it directly (i.e. they accelerate by the factor), for other
profiles it should hold that a higher acceleration factor leads to a faster
pointer. Typically, 1 is unaccelerated and values up to 5 are sensible.
.TP 7
.BI "Option \*qAccelerationThreshold\*q \*q" integer \*q
Set the threshold, which is roughly the velocity (usually device units per 10
ms) required for acceleration to become effective. The precise effect varies
with the profile however.
