+Subject: [PATCH] dix: Add unaccelerated valuators to the ValuatorMask
+
+Allows a mask to carry both accelerated and unaccelerated motion at the same
+time.
+
+This is required for xf86-input-libinput where the pointer acceleration
+happens in libinput already, but parts of the server, specifically raw events
+and DGA rely on device-specific unaccelerated data.
+
+To ease integration add this as a second set to the ValuatorMask rather than
+extending all APIs to carry a second, possibly NULL set of valuators.
+
+Note that a valuator mask should only be used in either accel/unaccel or
+standard mode at any time. Switching requires either a valuator_mask_zero()
+call or unsetting all valuators one-by-one. Trying to mix the two will produce
+a warning.
+
+The server has a shortcut for changing a mask with the
+valuator_mask_drop_unaccelerated() call. This saves us from having to loop
+through all valuators on every event, we can just drop the bits we know we
+don't want.
