PointerMotionScaling

Scaling of pointer motion by an 8.8 fixed point value.

Provides a device specific mouse speed adjustment.

The scaling value is an 8.8 fixed point value, meaning that it is a 16 bit value with the value 0x0100 representing the value 1. The device firmware validate the scaling value and clip it to a reasonable range so that pointer motion cannot be set to an excessively fast or slow setting. A recommended valid range is 16x (0x1000) as the upper limit and 1/16x (0x0010) as the lower limit.
