QZion is a canvas abstraction used by and made for QEdje. As it is an abstraction, different implementations can exist, making it possible to optimize QEdje for different platforms/devices.

Currently an implementation, based on KGameCanvas (from libkdegames) exists, but work is being done on providing an implementation using QT's QGraphicsView.

The KGameCanvas-based implementation is very lightweight and works relatively well on embedded devices, where QGraphicsView is currently slow and not yet optimized for.
