Object picker
Object picker is a component that allows an entity to interact with the mouse pointer. This component does not interact with the previously described input API directly. For example, you don't need to provide a mouse device for it. All you need to do is to attach the ObjectPicker component to an entity that also contains a mesh. The signals from ObjectPicker will notify you about input events related to this entity:
| Signal | Explanation |
| clicked(pick) | The object was clicked. |
| pressed(pick) | The mouse button was pressed over the object. |
| released(pick) | The mouse button was released after pressed(pick) was triggered. |
| moved(pick) | The mouse pointer was moved. |
| entered() | The mouse pointer entered the object's area. |
| exited() ... |
