Merge lp:~macslow/notify-osd/fix.810325 into lp:notify-osd/oneiric

[Mirco Müller]

The background-color for a bubble will be read from a GSettings key ("com.canonical.Unity average-bg-color"). If that key isn't available the old dark grey will be used.

To ensure there's enough contrast between the bubble background and its contents only 75% of the read background-color is applied.

For this to work Unity with lp:~unity-team/unity/fix.810325 merged in has to be running.

[Sebastien Bacher (seb128)]

One issue with that patch is that it makes notify-osd depends on unity by the way gsettings schemas are working (or you would need to do hacks to check if the unity schemas is installed and fallback to a default value if it's not). Wouldn't it make sense to add an unity dbus method to export the value and query the value over dbus? it would make easier to do handle non unity scenarios.

otherwise small comment, it seems your indentation is mixing tabs and space

apply only 75% of the average-color to keep enough contrast to the text and icon, pick up the average upon startup... not only on wallpaper-change
