=================================================
the position obtained from the SoPath of the picked point when entering
the combined icon object is not the center of the icon, what leads to
wrong preselection or no preselection at all.
This commit uses the translation of the Constraint node, which is the same that
is used to locate the constraint icons on the screen in the first place.
========================================
Now the Grid is calculated based on the maximum semiaxis length. Grid is recalculated on every redraw of the Sketcher.
========================================
Axes size was bounded to the boundingbox of the underlaying 2D shape. However, this does not even get updated in no update mode and provides unreliable values.
The axes calculation now:
- is coded to be the same size and fully symmetric.
- is coded to be minimum 100 mm semiaxis, which gives a good impresion for empty sketches with default zoom.
- is coded to grow with the largest of the semiaxes.

set/get/toggle python interface to enable to set the virtual space status of a constraint via SketchObject.

Deletion of coincidents rely on selected vertex. The original code was trying to delete a coincident without checking whether one was there.
The implementation now relies on checking whether a coincident is present.
===========================================================================
Cleaning up ViewProviderSketch, as relative mode is never used for points.
Adapting the recalculation of the initial solution only to non-relative cases.
For relative movement cases (movePoint with relative=true) no cases where such a solution will be advantageous have been identified
and applying a similar solution involves changing the current behaviour too much, as to run the risk of introducing further bugs.
Decision to be revised if such cases where an advantage can be found are discovered.
