animateTransform and attribute to
Test of the correct additive default behaviour of to animations.
A circle moves on a quadratic path using two to animateTransforms in
x direction and one simple animate for cy.
The animation for cy and the first to animation for
x is repeated two time, the second to animation for x just 1.5 times.
Note that the second to animation is frozen on the
half way. Because it has higher priority, the whole animation in x
is frozen.
The path is given in gray for comparison, thin line for the first turn,
thick line for the second turn.
If the red center of the circle becomes visible, an error
occured.
