Is KWin rocket science?

“This weekend I played around with adding a slight animation to
the BoxSwitch effect when the selection changes and when new
windows are opened or existing closed. Here’s the video:

“The BoxSwitch effect is now animating the selection when
pressing Tab. It’s moving instead of jumping as before. Another
change is that all thumbnails adept to changes in their geometry
when a new window is added or an existing is removed. They slide to
the new position instead of just jumping there. Isn’t that
elegant?

“On this effect I worked together with a new possible KWin
developer who does not know anything about OpenGL. So what do you
think how many lines of OpenGL code this new animation contains?
100? 50? 10? or maybe 1? No you don’t need to know any OpenGL to
write hardware accelerated animations in KWin.”
