Way to get location of tap outside view?

I am looking at OnOutsidePhotoTapListener and `void onOutsidePhotoTap(ImageView imageView);`:

https://github.com/Baseflow/PhotoView/blob/master/photoview/src/main/java/com/github/chrisbanes/photoview/OnOutsidePhotoTapListener.java

## 🚀 Feature Requests

This callback appears to only say what ImageView the tap was outside of but not where it was.

### Contextualize the feature / Describe the feature.

It would be useful to get, if not the exact location of the tap, the nearest point *to* the tap. As it is, if the user is trying to tap on a point on the edge of the photo view they might have to try several times accidentally tapping on the wrong side of the border.

Expected behavior, if this is possible: onOutsidePhotoTap should have the same signature as `void onPhotoTap(ImageView view, float x, float y);`. The coordinates returned should (probably) be clamped to the range 0..1, 0..1.
