    | larscwallin.inx.extractelements version 0.1 extracts all selected SVG Elements to file and/or displayed as a string in the
    | Inkscape GUI.

    || UPDATE 130506
    Added movePath method which moves all paths to 0,0 coordinates regardless of their original placement.

    If no elements are selected, the extension now defaults to exporting any visible layers. Precondition for this is that layers have been hidden and then shown again at some point as Inkscape currently does not add this meta data by default.
    || UPDATE 130510
    |||| Added option to keep the canvas size of the original drawing when exporting.
    (Previously each exported drawing was sized according to its elements bounding box)
    |||| Bug fixes
