required by the SVGT1.2 test suite and Opera's behaviour.

<!-- by animation
The behaviour at this point is not clear. The definition of by-animation
is:
"simple animation in which the animation function is defined to offset
the underlying value for the attribute, using a delta that varies over
the course of the simple duration, starting from a delta of 0 and ending
with the delta specified with the by attribute." (SMILANIM 3.2.2)
Therefore it might seem like by-animation of by="1" means to ADD to the
underlying scale factor. Furthermore, the underlying scale factor when
not otherwise specified might seemt to be 1, but the SVG WG have decided
it's 0. This is inconsistent with the definition of addition for
animateTransform (post-multiplication of matrices) but it is the
behaviour required by SVGT1.2 test suite and used by Opera.
The following animation should go from 0 to 4, over 2s so at t=1s, the
scale factor should be 2.
