compare spline animateMotion and animateTransform
Comparing spline animateMotion with animateTransform
for a rectangle.
animateTransform is blue and covers completely
the red animateMotion. Dark red uses the mpath element,
light red the path attribute and red values
The path consists of a triangle indicated in gray.
The paths are using explicitely the command Z to close
the path. In a linear animation the Z command consumes
time too, even if the length of the subpath is zero.
If something red gets visible, an error is occured.
dark red: animateMotion calcMode spline using mpath
light red: animateMotion calcMode spline using path
lighter red: animateMotion calcMode spline using path with a zero length Z
red: animateMotion calcMode spline using values
blue: animateTransform calcMode spline
