a swipe gesture object
A swipe gesture object notifies a client about a multi-finger swipe gesture detected on an indirect input device such as a touchpad. The gesture is usually initiated by multiple fingers moving in the same direction but once initiated the direction may change. The precise conditions of when such a gesture is detected are implementation-dependent.
A gesture consists of three stages: begin, update (optional) and end. There cannot be multiple simultaneous hold, pinch or swipe gestures on a same pointer/seat, how compositors prevent these situations is implementation-dependent.
A gesture may be cancelled by the compositor or the hardware. Clients should not consider performing permanent or irreversible actions until the end of a gesture has been received.

multi-finger swipe begin
Parameters
This event is sent when a multi-finger swipe gesture is detected on the device.
Definition at line 5623 of file wayland-server-protocol-unstable.cpp.
multi-finger swipe end
Parameters
This event is sent when a multi-finger swipe gesture ceases to be valid. This may happen when one or more fingers are lifted or the gesture is cancelled.
When a gesture is cancelled, the client should undo state changes caused by this gesture. What causes a gesture to be cancelled is implementation-dependent.

Retrieve the interface name (class) of a resource object.
Returns
Get the associated client
Returns
Get the internal ID of the resource
Returns
Get interface version
Returns
destroy the pointer swipe gesture object

Post 'not enough memory' error to the client
If the compositor has not enough memory to fulfill a certail request of the client, this function can be called to notify the client of this circumstance.
Check whether this wrapper actually wraps an object.
Returns
multi-finger swipe motion
Parameters
This event is sent when a multi-finger swipe gesture changes the position of the logical center.
The dx and dy coordinates are relative coordinates of the logical center of the gesture compared to the previous event.
