* 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. --------- Co-authored-by: Tig <tig@users.noreply.github.com>
