* Post an event to the client's object referred to by 'resource'.
* 'opcode' is the event number generated from the protocol XML
* description (the event name). The variable arguments are the event
* parameters, in the order they appear in the protocol XML specification.
*
* The variable arguments' types are:
* - type=uint: uint32_t
* - type=int: int32_t
* - type=string: (const char *) to a nil-terminated string
* - type=array: (struct wl_array *)
* - type=fd: int, that is an open file descriptor
* - type=new_id: (struct wl_object *) or (struct wl_resource *)
* - type=object: (struct wl_object *) or (struct wl_resource *)
