[Insight-developers] Transform::SetParameters() and Modified()

[Miller, James V (GE, Research)]

Should the SetParameters() method in a Transform call Modified()?

I suspect that we avoid calling Modified() on SetParameters() because it
is called in the inner loop. I think ScaleTransform, TranslateTransform,
and VersorRigid3DTransform to not call Modified() on a call to
SetParameters() but MatrixOffsetTransformBase does.

Depending on the answer to this, there may be a bug in the
GradientDifferenceImageToImageMetric which runs a small pipeline inside
the GetValue() method which relies on the Transform being Modified by a
call to SetParameters().
