the ClutterStage:perspective property only controls the perspective
transformation; if you want an orthonormal projection you will need to
use the ClutterStage:transform or ClutterStage:child-transform
properties (available in Clutter 1.12), or override the
ClutterStage::apply_transform and ClutterStage::paint virtual
functions through sub-classing.
