Force a layout pass if the display rotation changes 

 Bug: 7687209
 DisplayRotation is used to map camera orientation to the display and is
 updated in layoutContentPane(). However, in the case of a 180 rotate
 framework doesn't send an onConfigurationChanged nor does the layout
 dimensions change, thus layoutContentPane doesn't fire and we don't
 update mDisplayRotation, resulting in an upside-down preview. To handle
 this, check each draw whether or not the display rotation has changed
 and if it has force a layout pass.
