Structure that contains details common to INPUT_CLASS_MTOUCH input events.
Synopsis:
typedef struct mtouch_event {
input_event_e event_type ;
_Uint64t timestamp ;
_Uint32t seq_id ;
_Uint32t contact_id ;
_Int32t x ;
_Int32t y ;
_Uint32t width ;

Data:
- input_event_e event_type
- The event type of the INPUT_CLASS_MTOUCH event.
- _Uint64t timestamp
- Timestamp, based on realtime clock, when the INPUT_CLASS_MTOUCH event occurred.
- _Uint32t seq_id
- The sequence number for the event; seq_id is incremented each time a new touch-related event occurs.
- _Uint32t contact_id
- The order of occurrence for multiple touch contacts.
- _Int32t x
- The x screen position, in pixels, for the event.
- _Int32t y
- The y screen position, in pixels, for the event.
- _Uint32t width
- The width, in pixels, of the touch area.
- _Uint32t height
- The height, in pixels, of the touch area.
- _Uint32t orientation
- The orientation of the contact.
- _Uint32t pressure
- The pressure of the touch contact, ranging from 0 to 2^32 - 1.
- _Uint32t contact_type
- The contact type.
Valid contact types are of type contact_type_e.
- _Uint32t select
- The selected buttons.

Description:
The mtouch_event structure represents information that is common to all input events of class INPUT_CLASS_MTOUCH. This information is provided by the input device driver whenever an INPUT_CLASS_MTOUCH event occurs.
