Import Elements Transform Attribute

In many cases svg elements, created in other applications, can be reused/imported into your current application. Typically, it must first be resized to 'fit' your current svg size. This uses getBBox() and the transform attribute to resize it and place it where desired.
Scenerio:
You have placed the path element for the outline of the U.S. from an svg world map. It is presently located in your current svg application.
It can be resized and transformed so it fits this current svg viewPort.
Let's assume you want to have it centered in the current svg drawing, and be 390 px wide.
(Note: It is best to remove any previous transforms on the elements.)
