////////////////////////////////////////////////////////////////////////
// nsSVGTransformSMILType
//
// Operations for animating an nsSVGTransformList.
//
// This class is confused somewhat by the fact that:
// (i) An <animateTransform> element animates an SVGTransformList
// (ii) BUT <animateTransform> only allows the user to specify animation values
// for an SVGTransform
//
// This may be rectified in a future edition of SVG but for now it means that
// the underlying value of an animation may be something of the form:
//
// rotate(90) scale(2) skewX(50)
//
// BUT the animation values can only ever be SINGLE transform operations such as
//
// rotate(90)
//
// (actually the syntax here is:
// <animateTransform type="rotate" from="0" to="90"...
// OR maybe
// <animateTransform type="rotate" values="0; 90; 30; 50"...
// OR even (with a rotation centre)
// <animateTransform type="rotate" values="0 50 20; 30 50 20; 70 0 0"...)
//
// This has many implications for the number of elements we expect in the
// transform array supplied for each operation.
//
// For example, Add() only ever operates on the values specified on an
// <animateTransform> element and so these values can only ever contain 0 or
// 1 TRANSFORM elements as the syntax doesn't allow more. (A "value" here is
// a single element in the values array such as "0 50 20" above.)
//
// Likewise ComputeDistance() only ever operates within the values specified on
// an <animateTransform> element so similar conditions hold.
//
// However, SandwichAdd() combines with a base value which may contain 0..n
// transforms either because the base value of the attribute specifies a series
// of transforms, e.g.
//
// <circle transform="translate(30) rotate(50)"... >
// <animateTransform.../>
// </circle>
//
// or because several animations target the same attribute and are additive and
// so are simply appended on to the transformation array, e.g.
//
// <circle transform="translate(30)"... >
// <animateTransform type="rotate" additive="sum".../>
// <animateTransform type="scale" additive="sum".../>
// <animateTransform type="skewX" additive="sum".../>
// </circle>
//
// Similar conditions hold for Interpolate() which in cases such as to-animation
// may have use a start-value the base value of the target attribute (which as
// we have seen above can contain 0..n elements) whilst the end-value comes from
// the <animateTransform> and so can only hold 1 transform.

<!-- 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.
