Subject: [PATCH] Timeline: rearrange drawing in accordance to construction

...since the construction is determined now (and was worked out in FreeCAD),
the SVG will serve to document the construction; thus the drawing
primitives are rearranged to use the unscaled reference coordinates
to be extracted from the FreeCAD document; all scaling and placement
in the SVG document will be applied through common groups.
