[PATCH] Allow ConstantDeceleration and AdaptiveDeceleration < 1.0

[Eric Biggers]

As documented in xorg.conf(5), a value of ConstantDeceleration between 0
and 1 will speed up the pointer.  However, values less than 1 actually
had no effect.  Fix this.

For consistency I also made the same change for AdaptiveDeceleration,
which had the same behavior.

Note that this bug only affected "ConstantDeceleration" as configured
through xorg.conf, not "Device Accel Constant Deceleration" as configured
through xinput.
