Pass the SVG to the editor, using
editor.svgCanvas.setSvgString(selected);
instead. (Suggested by Jeff Schiller)
Fix a bug with line and freehand tools caused
by activating foreignObject tool. (Again, fix
due to Jeff)
Sync with SVG-Edit.
They are now selectable, draggable, resizable
and rotatable.
The MathML content behave strangely when you
resize, but snaps back to its correct size when
you let go of the mouse.
(Resizing the MathML involves changing the font-size
on the containing foreignObject. No interface for
that, yet.)
