Description Brien Dieterle 2017-08-30 05:29:54 UTC
This is only a problem in Mac OS.  Tested Linux with same hardware.

Tried 2.7.11 from website, as well as latest dev build in MacPorts 1.19.99.1.

Steps:
MacOS 10.11.6
Install wacom drivers from wacom
attach wacom tablet and stylus with tilt support
xinput test <dev id of pen>
observer x and y tilt values.

Expected:  X-Tilt should have negative values tilted left,and positive values tilted right.  Y-Tilt should have negative values tilted forward, and positive values tilted back (towards the user).
Actual:  The Y values are inverted.

Windows and Linux conform to the document from Wacom.
