Derived from App::DocumentObjectT to add support of sub object
Also some minor changes to App::DocumentObjectT
Changed Gui::SelectionChanges to make use of SubObjectT
while fixing a SVG export issue for techDraw I noticed that some SVG files have program-dependent (and thus not clean) code in it. These are traces of the programs Sodipodi and Inkscape, like e.g. this line:
inkscape:export-filename="/home/yorik/PartDesign_Groove.png
This is unnecessary and FC should not use program-dependent code in the SVG but use instead plain SVG strictly following the SVG specification.
This PR transforms the few affected SVGs to a plain version.
* Relaxed valid base shape requirement, as long as it can return a
shape using part.getShape()

observer
