Detailed Description

These are the kinds of resulting gestures that we recognize.

Enumerator:

MASK_BASE	Special bit masks for classification of types of gestures. For masking off low byte for raw event
MASK_HELD	Event involves device being held 'down' for some period.
MASK_RELEASED	Event involves a 'release' up of input.
MASK_MOVED	Event involves some movement input device.
MASK_MULTI	Event involves multiple inputs, i.e. multi-finger touch
MASK_MAYBE	Hint that event is conditional on a later timeout.
MASK_REPEAT_DOUBLE	Base event occurred twice within short period.
MASK_REPEAT_TRIPLE	Base event occurred three times in short period.
INVALID	The set of recognized gesture values. Denotes an invalid value
NONE	Base value, no gesture has occurred yet.
HOVER	Denotes a pointer hovering on screen but no press/click yet.
PRESS	Pointer has been pressed down, clicked.
HOLD	Pointer has been kept down past a particular timeout.
RELEASE	Pointer has been kept down past a longer timeout. Pointer has been released, let up
MAYBE_TAP	A short tap occurred, but we haven't confirmed user intent yet due to timeout or new event.
TAP	A brief tap was confirmed (either because double-tap delay passed, or other event began).
DRAG	Pointer is down and has moved from its starting point enough to intend to 'drag'.
FLICK	Pointer was released during accelerating motion vector.
DOUBLETAP	Pointer has come back down again within a small delta distance and time of a prior tap.
