Mismatch between documentations

There is a mismatch between the old Win SDK (2.0), new Win SDK, and Mac SDK about the sign of axes of translation and rotation.

All documents state: "The home position for the device is with the negative Z-axis pointing towards the screen."

In bold are the cases that match the above sentense (mostly old Windows SDK).

oldWin newWin Mac

Translations:

Device illustration old new Mac
arrow pointing away from the screen Translate Z-axis 0 to -MAX Translate Z-axis 0 to MAX Translate Z-axis 0 to -MAX
arrow pointing towards the screen Translate Z-axis 0 to MAX Translate Z-axis 0 to -MAX Translate Z-axis 0 to MAX
arrow pointing up Translate Y-axis 0 to MAX Translate Y-axis 0 to MAX Translate Y-axis 0 to -MAX
arrow pointing down Translate Y-axis 0 to -MAX Translate Y-axis 0 to -MAX Translate Y-axis 0 to MAX
arrow pointing right Translate X-axis 0 to MAX Translate X-axis 0 to MAX Translate X-axis 0 to MAX
arrow pointing left Translate X-axis 0 to -MAX Translate X-axis 0 to -MAX Translate X-axis 0 to -MAX

Rotations:

arrow turning left Rotate Z-axis 0 to -MAX Rotate Z-axis 0 to MAX Rotate Z-axis 0 to -MAX
arrow turning right Rotate Z-axis 0 to MAX Rotate Z-axis 0 to -MAX Rotate Z-axis 0 to MAX
arrow turning clockwise when the user looks at the table Rotate Y-axis 0 to -MAX Rotate Y-axis 0 to -MAX Rotate Y-axis 0 to MAX
arrow turning counter clockwise when the user looks at the table Rotate Y-axis 0 to MAX Rotate Y-axis 0 to MAX Rotate Y-axis 0 to -MAX
arrow turning down towards the user Rotate X-axis 0 to MAX Rotate X-axis 0 to MAX Rotate X-axis 0 to MAX
