Commit 25a9f39 ("tablet: fix the airbrush slider range") has caused libinput to start normalizing distance values to the range [-1, 1] instead of the expected [0, 1]. This can be easily seen by bringing a tool into prox while running libinput-debug-events: event16 TABLET_TOOL_PROXIMITY +2.85s 91.11*/91.11* distance: 0.30* rotation: 0.00* wheel: 15.00* (1) mouse (0xa00, id 0x17) proximity-in axes:drw btn:LMRSdEx event16 TABLET_TOOL_AXIS +2.87s 91.21*/91.21* distance: 0.30 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +2.87s 91.28*/91.28* distance: 0.30 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +2.88s 91.34*/91.34* distance: 0.21* rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +2.89s 91.34/91.34* distance: 0.21 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +2.90s 91.46*/91.46* distance: 0.21 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +2.91s 91.46/91.46* distance: 0.11* rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +2.92s 91.58*/91.58* distance: 0.11 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +2.93s 91.64*/91.64* distance: 0.02* rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +2.94s 91.75*/91.75* distance: 0.02 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +2.95s 91.83*/91.83* distance: 0.02 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +2.96s 91.92*/91.92* distance: -0.08* rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +2.97s 91.92/91.92* distance: -0.08 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +2.98s 91.92/91.92* distance: -0.17* rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +2.99s 91.84*/91.84* distance: -0.17 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +3.00s 91.74*/91.74* distance: -0.17 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +3.01s 91.60*/91.60* distance: -0.30* rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +3.03s 91.57*/91.57 distance: -0.30 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +3.04s 91.57/91.57* distance: -0.30 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +3.05s 91.57/91.57 distance: -0.40* rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +3.06s 91.57/91.57* distance: -0.40 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +3.07s 91.62*/91.62 distance: -0.40 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +3.11s 91.66*/91.66 distance: -0.40 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +3.15s 91.74*/91.74 distance: -0.40 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +3.15s 91.74/91.74* distance: -0.40 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +3.17s 91.74/91.74* distance: -0.40 rotation: 0.00 wheel: 0.00 (0) event16 TABLET_TOOL_AXIS +3.19s 91.85*/91.85 distance: -0.49* rotation: 0.00 wheel: 0.00 (0)
