Animation of transform types
animateTransform, by.
A blue square and a test text are transfomed with a matrix.
After 3s an additive animateTransform with a scale by -1.5,-1.5 and
a duration of 10s and calcMode linear is applied to the blue group.
This means, after 3s the group morphes to a mirrored
group.
matrix itself is not animatable, but it is the underlying
value for the animateTransform.
If a red group becomes visible, an error occured.

simple animation just for comparison
