- Merge was a little involved, ran SlateViewer and things seem to be working as expected
ListView improvements
- Added horizontal layout option to both SListView and STileView.
- Added smooth inertial scrolling. Doing so naturally requires more refreshes, so it's not intended for use in perf-sensitive scenarios and is disabled by default.
- Added option to establish a consistent fixed offset when scrolling (to, for example, ensure the top item is always flush with the top of the list, or that the bottom 25% of the preceeding item is always visible above). Note that enabling this will override the NavigationScrollOffset property, as the two concepts fully conflict.
- Exposed all new functionality to the UMG counterparts of the slate lists
- Updated SlateViewer's ListView testing tab to include a horizontal list, a horizontal tile view, and options for enabling animated scrolling and fixed offsets. Also tinkered a bit with the default sizing and open tab, as the default size seemed universally too small.
