[Emmanuele Bassi <ebassi src gnome org>]

commit 80dd60ecbb4b7cf0fcb00f663a33662fcb3f49b8
Author: Emmanuele Bassi <ebassi linux intel com>

    test-swipe-action: Clean up the test code
    
    Remove unused code, and be more strict at discarding swipes on
    constrained actors.
    
    Add a note on the behaviour of each rectangle/action pair.
