* This does the initialization
* and layout of the dialog used for transforming SVG objects. It
* consists of 5 pages for the 5 operations it handles:
* 'Move' allows x,y translation of SVG objects
* 'Scale' allows linear resizing of SVG objects
* 'Rotate' allows rotating SVG objects by a degree
* 'Skew' allows skewing SVG objects
* 'Matrix' allows applying a generic affine transform on SVG objects,
* with the user specifying the 6 degrees of freedom manually.
*
* The dialog is implemented as a Gtk::Notebook with five pages.
* The pages are implemented using Inkscape's NotebookPage which
* is used to help make sure all of Inkscape's notebooks follow
* the same style. We then populate the pages with our widgets,
* we use the ScalarUnit class for this.
