Camera Tile : Close on flip/switch

Currently the camera tile only checks whether the
container panel is fully expanded. This doesnt take into account
when the user swipes to another panel via handle bar swipe, or by
pressing the switch button in the top right of the drawer.

Reproduction steps :
    Go to quick settings panel
    Enable camera tile
    Switch to notifications via swipe or switch button
    Camera preview stays persistent behind drawer

This patchset also makes the view hierarchy lookups one time, rather than
on each runnable run which is quite frequent (100ms).

use a layer drawable part:
in preperation to the new navbar and statusbar transparency
managment which will come it is more consistent on custom image
and color fill on lockcreen to use a layerdrawable to add the
shadow on top of the image to keep on transparency of the background
the shadow like it is suggested by google
