power: Update level bar offsets for those used by UPower
The default levels (and thus colours) used by the GtkLevelBar are:
GTK_LEVEL_BAR_OFFSET_LOW, GTK_LEVEL_BAR_OFFSET_HIGH and GTK_LEVEL_BAR_OFFSET_FULL, with values 0.25, 0.75 and 1.0 respectively.
For devices (eg. not the main batteries), those offsets should be 0.05
and 0.1
.
For laptop batteries and UPSes, those offsets should be 0.03
and 0.1
.
Full (and a nice green colour) should probably be 0.8
and above, so that nearly full batteries still appear as green.
