Subject: [PATCH] wacom: fix the dimensions for the Spark

The reachable range is 2100x14800, highest pressure is 1023. Unlike the slate
the paper block still affords to address almost the whole range even though
the paper is slightly narrower than the range - but it can slide left/right by
about 5mm.
