BDisp 85c92f4b0d Fixes #2959. Some of the scroll features on v1 are broken. (#2960)
* Add GrabMouseEventArgs for GrabbingMouse and UnGrabbingMouse events.

* Implementing GrabbingMouse and UnGrabbingMouse in Toplevel class.

* Fix contentBottomRightCorner to draw with the right color.

* Fix a typo.

* Fix ListView to allow scrolling.

* Add a comment to explain an extra column for the cursor at the end of line.

* Add unit tests for GrabbingMouse and UnGrabbingMouse events.

* Add unit test for a Window inside a non Toplevel.

* Removes GrabMouseEventArgs.

* Prevents throwing an exception if not subscribed.

* GrabMouse must be first called before set the dragPosition.

* Add unit test to test null on GrabbingMouse and UnGrabbingMouse.

* Fix event name.

* Prevents a toplevel to overflows his bounds to allow it can be drag.

* Fix unit test.
