ResolutionChangeDetector now does not update its internal state. There is no impact because Reset() is always actively called. So this change renames ResolutionChangeDetector to ResolutionTracker, and rename the IsChanged() function into SetResolution(), which returns true if a replacement happened. Internally it always records the latest DesktopSize. Customers of this class can still use SetResolution() function to check whether a DesktopSize change happened.
