Some basic animation tests to help see what kinds of animation are possible on what architectures. Usage: CLUTTER_SHOW_FPS=1 gjs clutter.js [crossfade/slide] [1080/720] GDK_DEBUG=frames gjs gtk.js [crossfade/slide] [1080/720] You can choose between a cross fade and a slide, and a 1080 or 720 image asset to animate. (The screen resolution and not the asset size should really determine frame rate, but just in case.) Clutter will print out a proper frame rate, whereas GTK will print out a series of intervals between draw updates. During an animation these should be at 16 milliseconds for 60 FPS. Click to trigger a slide. Press any key to quit.
