Resolve the oldHwProx puzzle
Change oldHwProx to oldCursorHwProx to better reflect its use.
oldCursorHwProx keeps the hardware in/out prox state so we can
set the MaxCursorDist for the next round of relative cursor
movement when tool first comes in prox.
For Protocol 5 devices, distance is reported as the maximum
when tool is first detected. Then it is gradually reduced to 0
when getting closer to the tablet. Protocol 4 is the opposite:
distance is 0 when tool is first in prox. The value increases
as the tool gets closer to the tablet.
The maximum distance (wcmMaxDist) is model specific. They are
retrieved from the kernel.
