From the article:

One of the most notable and enduring Linux desktop paradigms has been desktop effects: the coupling of various desktop environments with graphical niceties, also known as “eye candy.” With the advent of the XComposite extension in the mid 2000s, mainstream eye candy was taken to new levels through a small project called Compiz which used the texture from pixmap extension to apply hardware-accelerated effects to windows on the fly.

Partial implementations of it have been developed for Enlightenment a couple times over the lifetime of E17 and onwards. However, none of these are great solutions in today’s modern world of GLES/EGL, Wayland, and embedded devices. Currently, Compiz uses Xlib internally as well as GLX, enforcing a dependency on X11 and the Xserver. Furthermore, given the server-side location of the effect handling, this will not play too nicely with the client-oriented Wayland protocol.

And so it was, armed with this knowledge, that a pair of procrastinating-yet-ambitious Samsung Open Source Group graphics engineers set out to improve the Wayland world with client-side, window, post processing effects. The goal: implement wobbly windows using the client-side decoration region and a lot of elbow grease.
