Explicitly indicate that if parameter diagnosis must be silent=false in order to debug,
then the lauch policy during the debug must be set to deferred in order to avoid concurrent
access to Base::Console which is not thread-safe.

When a parameter belonging to a blocked geometry is present in several
dependency groups and there are other fixed parameters one or more of
the dependency groups, it is not enough to remove that parameter, from
the one or more dependency groups. The removal of a parameter may only
satisfy one dependency group. Removing a single parameter creates a
new different dependency group.
Solution:
If the first blocked parameter in a group is already set for removal,
continue searching for other blocked parameters, until one not searched
for removal is found.

addSymmetric will now only transfer Vertical and Horizontal constraints if the reference axis is either
- the HAxis
- the VAxis
- a Vertical line
- a Horizontal line
======================================================
With the new solver ability to identify groups of dependent parameters, even with SparseQR, it is now possible to properly implement Blocked constraint (blocked geometry state/mode).
This comes at the cost of two consecutive diagnosis (4 QR decompositions, running in parallel by pairs, so the double of time than when not using any blocked constraint).
A first diagnosis identifies the groups of dependent solver parameters.
If any of these groups comprises a parameter affected by a blocked constraint, the parameter is fixed. As only one parameter from each group is fixed, there are no (partly) redundant parameters involved.
Then the new adapted system is solved.
==============================
Do not copy/array internal alignment geometry if the geometry it defines is not part of the operation. Silently ignore it.
If the reference for the operation is one such geometry (or it is the only one), then abort the operation.
================================================================================
Internal Alignment constraint mirroring was never implemented. With the enhancements
brought with implementation of geometry extensions in the sketcher, this lack of
implementation became a crash, as geometry was marked as being internal alignment, while
no associated internal alignment constraint was created.
Restrictions:
- Internal alignment geometry is only to be mirrored if the geometry it defines is also
being mirrored. Internal alignment geometry is otherwise skipped. This is because it
does not make sense to have a pole without a b-spline, or a major axis of a ellipse without
an ellipse.
