Recompute slide offset from sliding view top when drag state becomes idle. Some slower devices were missing the final onPanelDragged events so the onPanelExpanded, onPanelAnchored & onPanelCollapsed events were not being fired.
Removed log statement that was accidentally left in.
Set slide state before calling onPanelXxx event callbacks. Calls to isAnchored() and isExpanded() should return the correct value if called during the onPanelXxx event callbacks.
