Add configurable x/y resolution to fix sensitivity on wide touchpads.
Synaptics uses anisotropic coordinate system. On some wide touchpads
vertical resolution can be twice as high as horizontal which causes
unequal sensitivity on x/y directions.
VertResolution and HorizResolution can be used to set the resolution.
The ratio of the values is used to compensate x/y sensitivity. The
properties are configured automatically if touchpad reports resolution
and if running on linux 2.6.31 or newer.
Fixes xorg bug #18351.
