-brightness needs to implement brightness_half_holo state
*fixed now in the patch { old assets should be removed also(any "appwidget" that doesn't have holo in it)}
Change-Id: I2c1e754f68cf321c5b3517ba92c8f235b418e696
The power widget now uses the fuzzy-edged widget background.
It has a resonable layout in portrait and landscape.
appwidget_inner is the background for a button on the inside, with a border on the left.
appwidget_outer is the background for a button on the outside (i.e. leftmost); it
does not have a border.
This widget allows uses to turn on/off bluetooth, wifi, gps, and sync,
and adjust brightness without going through the settings menu.
The widget provider updates the settings when the buttons are pressed.
The widget provider is also a receiver for events indicating that the
status was updated elsewhere and the buttons need to be changed.
