Fix off by one errors in touch motion ranges. (DO NOT MERGE)

Report inclusive minimum and maximum ranges for all
axes including X and Y.

Set mouse pointer bounds to 0..width-1, 0..height-1.

Rotate touch and mouse positions more carefully, paying attention
to the maximum bounds when calculating the complement of an axis.

Simplified the InputReader somewhat and removed support for a
couple of poorly defined input device configuration parameters.
We now assume that the touch device provides useful absolute axis
ranges for the X and Y axes since the alternative does not actually
make sense.
