Detailed Description

The current information about a pointer.

This struct is used by PointerDataPacketConverter to fill in necessary information for the raw pointer packet sent from embedding. This struct also stores the button state of the last pointer down, up, move, or hover event. When an embedder issues a pointer up or down event where the pointer's position has changed since the last move or hover event, PointerDataPacketConverter generates a synthetic move or hover to notify the framework. In these cases, these events must be issued with the button state prior to the pointer up or down.
