Expand description
Interface for touchscreen requests and events.
This interface is only provided once per device and where a client
requests ei_touchscreen.release the interface does not get re-initialized. An
EIS implementation may adjust the behavior of the device (including removing
the device) if the interface is releasd.
Note that for a client to receive objects of this type, it must announce
support for this interface in ei_handshake.interface_version.
