==============================
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.

Former mechanism with hasDependentParameters is not flexible enough for the new kind of information.
This commit further enhances the calculation of dependent parameters and dependent parameter groups by
caching the parameter-geoelement (GeoId, PointPos) relationship during geometry creation.
This commit provides traditional information whether a parameter is dependent via SolverGeometryExtension. New
enhanced information about groups of dependent parameters are available via the Sketch API.
================================================================================================================
std:async can take two policies one that forces the task to be run in parallel another (deferred) that runs the task
when wait is called on the future (kind of lazy evaluation).
Default policy is let the system decide (an or of both policies). Nobody is a better position than the system to know
its load and whether it is possible to run the task in parallel or not.
If the system cannot allocate a thread and parallel processing is enforced (as before this commit), then it will throw an
exception. In the present case we would catch it and run the task sequencially. Thus, it makes sense to let the system
decide from the beginning and save the exception and the handling.
In tests I have only managed to see it run in parallel with the default policy.

Diagnose constraints do not include among others driven constraints. This
function allows to know whether the solver is considering an empty matrix.
=================================================================================
Some geometry extensions do not provide a PyObject as they do not have a Python counterpart
as it would serve no purpose to have it.
This commit handles this situation making sure to provide the right error to Python
or to ignore the extension where appropriate.
==============================================================================
Deletion of a geometry having internal alignment geometry (B-Spline, Ellipse, ...)
involves calling a geometry deletion operation for each internal aligment constraint
in addition to the one of the geometry.
Before this commit, an update call was performed for each of these operations. Now,
there is a single update trigger operation after all the geometries are deleted.
===================================================
Currently the ID is a unique number without an specific use and it is
conceived to be taken over by future RT's Sketcher PRs.
Because of this, and not to interfere with RT's implementation, it is
not stored, but will be restored if attribute available.
Unrelated:
Similarly, ExternalGeometryExtension is also there conceived for RT's
future sketcher PRs, but it is not used.
==================================================================
GeometryExtension was originally designed to be serializable (save/restore). However,
GeometryMigrationExtension and ViewProviderSketchGeometryExtension have demonstrated the
usefulness of runtime-only GeometryExtensions.
The problem with runtime-only extensions being of a serializable type (GeometryExtension before
this commit) arises when Part::Geometry is to serialize the extensions and serialise the number
of extensions the geometry has. If runtime-only GeometryExtensions do not save a tag, then the
restore mechanism will expect more extensions that are actually in the XML file.
This commit makes GeometryExtension by default not serializable and deriving directly from
Base::BaseClass. A new class GeometryPersistentExtension is created, deriving from GeometryExtension
to provide serialisation. All Extensions requiring serialization derive from GeometryPersistentExtension
and those not requiring it from GeometryExtension directly.
This commit adapts all extensions to the new situation:
Part: GeometryDefaultExtension
Part: GeometryMigrationExtension
Sketcher: ViewProvierSketchGeometryExtension
Sketcher: SketchGeometryExtension and ExternalGeometryExtension
==============================================================================================================
This function is charged with receiving the construction information in a
GeometryMigrationExtension and setting the right data members of SketchGeometryExtension.
