WindowManagerService not propagating X and Y steps 

WindowManagerService received X and Y offset steps but failed to pass
them off to the relavent wallpaperservice.

Live wallpapers expect a valid value for xOffsetStep and yOffsetStep
when the WallpaperService.Engine::onOffsetsChanged function is called
As specified here:
https://developer.android.com/reference/android/service/wallpaper/WallpaperService.Engine.html
onOffsetsChanged(float,float, float, float, int, int)

See bug report:
