[DESK.CPL]
Resolution selection improvement patch by Mark Jansen:
- Fix a bug that allowed only a subset of resolutions to be visible.
- Update the preview on the fly when dragging the resolution slider.
- Fix a bug that prevented the monitor preview from properly invalidating the preview,
leaving the old preview partially visible.
Needs to be included in 0.4 branch.
CORE-10786
