ScalingFilterInterpreter: Special-case small mice moves
When using mice, it's frustrating when moving one device pixel moves
the cursor > 1 pixels on the screen. This CL avoids this problem by
looking for the special case of exactly 1 device pixel move, then
reducing the motion to just 1 pixel of motion.
We actually go a little under 1 pixel because it will be increased on
external displays later in the stack.
