Code review comment for lp:~elementary-pantheon/wingpanel/background-opacity-gala

Could you run "dbus-monitor | grep BackgroundChanged" in a terminal, change the background and look if something happens in the terminal? There should be some messages popping up.

I changed the min alpha value, the one that is taken when the wallpaper is found to be too light, to 0.3 now. Wingpanel will go fully opaque now when there's a maximized window. To me it appears very dark now, maybe you'll want to test if that is really the best way to do it. Also, maybe you could see if the logic for testing for a maximized window is already good enough or if we want to do something more complex. It will only go opaque currently if there's some window on the current workspace maximized. It won't go opaque for example when there are multiple non maximized windows obscuring the whole desktop.
