Trigger some code if the user tries to scroll past behind top / bottom content limit

[yusdacra]

Assuming I have a ScrollArea, and some content inside, what I want to do is trigger some code if the user tries to scroll past behind the bottom edge or the top edge. Is this possible? I have tried looking at how ScrollArea widget is implemented, but it's State isn't exposed to external consumers of the library; so I can't utilize it.

This hasn't been implemented it. Ideally ScrollArea::show would return a struct that contained a few flags indicating if the user tried to "overscroll" in either direction. It is likely not very hard to implement, though the code is a bit hairy :)
