Start a drag, providing a function to be called when the Wimp_DragEnd event is received and optionally a tracking function to be called on null polls in between times.
| *drag_end | Callback for when the drag terminates, or NULL for none. |
| *drag_track | Callback for mouse tracking during the drag, or NULL for none. |
| *drag_cancel | Callback for cancelling the drag, or NULL if the drag can't be cancelled. |
| *data | Data to be passed to the callback functions, or NULL. |

| void ro_mouse_kill | ( | void * | data | ) |
Kill any tracking events if the data pointers match the supplied pointer.
| *data | The data of the client to be killed. |

| void ro_mouse_pointer_leaving_window | ( | wimp_leaving * | leaving | ) |
Process Wimp_PointerLeaving events by terminating an active mouse track and passing the details on to any registered event handler.
| *leaving | The Wimp_PointerLeaving data block. |
If the ignore mask is set, we don't pass the event on to the client as it is assumed that it's a result of starting a Wimp_DragBox operation.
| *leaving | The Wimp_PointerLeaving data block. |

Start tracking the mouse in a window, providing a function to be called on null polls and optionally one to be called when it leaves the window.
| *poll_end | Callback for when the pointer leaves the window, or NULL for none. Claimants can receive *leaving==NULL if a new tracker is started before a PointerLeaving event is received. |

| *data | Data to be passed to the callback functions, or NULL. |
