+Subject: Fixed wacom emulation
+
+- for absolute mode, scale coordinates to the real device maximum values,
+since some drivers (on Haiku and Linux at least) need them as such,
+and the HID descriptor is boggus on some models anyway,
+- keep the coordinates even when no button is pressed, on real tablet
+the pen is sensed on the surface even without direct contact,
+and drivers expect this,
+- map left button to pressure according to what the Haiku driver wants,
+- map the right button to the pen button,
+- map the middle button to the eraser,
+- use asynchronous reporting as the hid code does, stops the Haiku driver
+(and probably others) from spending 50% cpu polling for changes.
