| controlID | The control ID for the handle. |
| position | The world-space position of the handle's start point. |
| rotation | The rotation of the handle. |
| size | The size of the handle in world-space units. |
| eventType | Event type for the handle to act upon. By design it handles EventType.Layout and EventType.Repaint events. |
Draw a dot handle. Pass this into handle functions.
On EventType.Layout event, calculates handle distance to mouse and calls HandleUtility.AddControl accordingly.
On EventType.Repaint event, draws the handle shape.
Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.
