initial transforms
Is there a reason that the initial transform stuff in SVGComponent and
GVTComponent were not fully implemented? It looks like there was a
start to do this. There is a method to get the initial transform, but
then it is just created as the identity transform in lots of places as
well.
I modified the code so that all uses of the "initialTransform" variables
were pointing to the instance in GVTComponent and everything (so far)
works fine.

This is not the way to go. What you describe is the default behaviour
of the canvas. What you want to do is ensure that after setMySize is
called the JSVGCanvas has the size you want it to have. It will
then adjust it's display to that size. By putting it in the viewport
it is becoming as large as it want's to be, you should put additional
logic in setMySize to query the visibleRect and set the preferred size
to that (or something along those lines).

We were experimenting with having the initial view set so that the whole
document fit within the user's window. I was wondering if using the
initial transform was the way to go, that way we don't have to start
rendering it one way, and then render it again, this time the way we
want.

Originally this held the viewbox transform but that has now
been moved into the SVG element. So it does appear that it is now
a useless remnent.

You could create an IDENTITY_TRANSFORM static final variable
and use that instead (it would be less potentially confusing).
