Tracking bug for a few cleanup items related to the SignalStrengthImageSource class in Ash UI:
(1) Consider applying the alpha for a connecting network icon in SignalStrengthImageSource instead of in ConnectingWirelessImage().
(2) Expose SignalStrengthImageSource; see the TODOs in network_icon.h above GetImageForConnectedMobileNetwork() and GetImageForDisconnectedCellNetwork().
(3) Share network icon background alpha with other icons in the system menu; see |kBgAlpha| in SignalStrengthImageSource.
