^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) * (e.g., stylus, mouse in reports 2, 3, 4, 5. We don't know
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) * for reports 1, 6.)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44) * what physical device reports for reports 1, 6.) Also enabled
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) * MOUSE and LENS tool button modes. Renamed "rubber" to "eraser".
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) * Feb 20, 2004, Bryan W. Headley.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) * v1.5 - Added previousJitterable, so we don't do jitter delay when the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48) * user is holding a button down for periods of time.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 50) * NOTE:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51) * This kernel driver is augmented by the "Aiptek" XFree86 input
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 52) * driver for your X server, as well as the Gaiptek GUI Front-end
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) * "Tablet Manager".
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 54) * These three products are highly interactive with one another,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 55) * so therefore it's easier to document them all as one subsystem.
