All Overlays are displayed over the current application and persist until hidden or destroyed.
Blocking overlays only block touches on the part of the screen they cover.
Non-blocking Overlays are also displayed over the Keyguard.
Dialogs are little popup windows which take all user input while they are displayed and can be dismissed with the Back key.
Activities are standard Android app views.
Offsets are percentages of the screen size with in the range 0-200, (0=100% left, 100=centre, 200=100% right).
Animation is only relevant for non-overlay scenes and when animations are enabled in Android settings.
