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.
* Support sub-object reference syntax using the following syntax,
Part.<<Box.>>.Placement
or, with sub-object label referencing
Part.<<$Cube.>>.Placement
* Extend indexing support, including range based indexing, e.g.
A1[B2+1][C3][D4:-1]
* Add new constants, None, True, true, False, false.
