Inner panics could make it hard to trouble shoot the issues and for some users it's not desirable. The inner panics were left only when they are used to `assert!` during development. This reverts commit 9f91bc413fe20618bd7090829832bb074aab15c3 which reverted the original patch which was merged without a proper review. Fixes: #500.

When using so called 'natural scrolling' (scrolling that acts like on a touch screen), this is what to expect:
|
|
|
|
Moving your finger downwards on a scroll wheel should make the window move down, and you should see a positive Y scroll value.
|
|
|
|
When moving fingers on a trackpad down and to the right, you should see positive X and Y deltas, and the window should move down and to the right.
|
|
|
|
With reverse scrolling, you should see the inverse behavior.
|
|
|
|
In both cases the example window should move like the content of a scroll area in any other application.
|
|
|
|
In other words, the deltas indicate the direction in which to move the content (in this case the window)."
