| originalMousePosition | The original mouse position of the IMGUI event, before it is transformed to the local element coordinates. |
| propagationPhase | The current propagation phase. |
| target | The target for this event. The is the visual element that received the event. Unlike currentTarget, target does not change when the event is sent to elements along the propagation path. |
