## produce a DragEnter event when reentering the dragged entity
when making a piano, i want dragging across the keys to trigger the
notes of each key, but currently if i drag out of a key, then back to
it, this will not work since the dragged entity gets filtered out
## Solution
- make DragEnter event work whenever there's an entry. if the user wants
to ignore the dragged entity they can compare `target` and `dragged`
## Testing
- tested this with a modified version of the 2d_shapes example. i added
an observer to the entities: (and added mesh picking plugin)
```rust
.observe(|t: Trigger<Pointer<DragEnter>>| {
info!("entered {}, started from {}", t.target(), t.dragged);
}
```
- i'm not sure if other things need more testing, or if this is wrong
completely and breaks other things i don't know of!
