Problem:
- While SketchObject inhibits intermediate updates during internal command execution, sometimes
a change in the selection (clear selection) in an intermediary step triggers an spurious update colour.
- There will be a final draw and this update colours at the end of the internal command.
- If the types of the constraints changed during the intermediary steps, it may happen that the constraint
coin nodes at a given position no longer correspond to the constraint type in the SketchObject property. This
may cause a attempt to access to a non-existing node or static casting a existing node to the wrong type.
Solution:
- Check the type of the constraint against the cached type. If not matching, cancel the color update.
* if determining the normal raises an exception then fall back to a default value
* when handling a Base::Exception then call its ReportException() function to get as much information as possible

Bug:
Subscription/Unsubscription of outside of edit mode parameters was missing.
So changing the edge color from settings required to restart FreeCAD.
Fix:
Subscribe/Unsubscribe from the relevant parameter group

==============================
- Constructor from const vector reference is not allowed to take ownership (as it should not delete the const pointer). The ownership parameter is removed.
- Factory method for const objects cannot either. So the ownership parameter is also removed.
=====================================
- GeometryFacade will throw when instantiated with a const Part::Geometry * that does not have a SketchGeometryExtension. It
cannot create it because it is not supposed to modify a pointer to a const object.
- Static functions will check the passed Part::Geometry * parameters and will throw if nullptr.
- GeometryTypedFacade constructor and factory methods to take owner parameter (defaulted to false) for consistency with GeometryFacade.
- The emplace style factory method will make the GeometryFacade take ownership of the emplaced Part::Geometry *. This should avoid memory leaks. The
user shall setOwner(false) if it needs to release() the underlying Part::Geometry * (to transfer ownership).
- Code comments made into doxygen documentation.
============================================================
Following new behaviour of highlighting root point on full constrained:
https://forum.freecadweb.org/viewtopic.php?p=555663#p555663
the rootpoint was lowered in virtual height with respect to the rest of points, so that
the color of any other overlapping point takes precedence.
However, this made it the same height as constraints, causing it to be unpickable in presence of
a colocated constraint:
https://forum.freecadweb.org/viewtopic.php?p=556114#p556114
Solution: Raise all points by one
=================================================================================
Apart from simplifying code, the allocated memory is not managed by the lifetime of the unique pointer owned by the GeometryFacade, preventing memory leaks.

Creation of EditModeCoinManager class and helpers.
In a nutshell:
- EditModeCoinManager gets most of the content of struct EditData
- Drawing is partly outsourced to EditModeCoinManager
- EditModeCoinManager gets a nested Observer class to deal with parameters
- A struct DrawingParameters is created to store all parameters used for drawing
- EditModeCoinManager assume responsibility for determining the drawing size of the Axes
- Preselection detection responsibility is moved to EditModeCoinManager.
- Generation of constraint nodes and constraint drawing is moved to EditModeCoinManager.
- Constraint generation parameters are refactored into ConstraintParameters.
- Text rendering functions are moved to EditModeCoinManager.
- Move HDPI resolution responsibility from VPSketch to EditModeCoinManager
- Move responsibility to create the scenograph for edit mode to EditModeCoinManager
- Move full updateColor responsibility to EditModeCoinManager
- Allows for mapping N logical layers (LayerId of GeometryFacade) to M coin Layers (M<N). This
is convenient as, unless the representation must be different, there is no point in creating coin
layers (overhead).
Refactoring of geometry drawing:
- Determination of the curve values to draw are outsourced to OCC (SRP and remove code duplications).
- Refactor specific drawing of each geometry type into a single template method, based on classes of geometry.
- Drawing of geometry and constraints made agnostic of scale factors of BSpline weights so that a uniform treatment can be provided.
Refactoring of Overlay Layer:
- A new class EditModeInformationOverlayConverter is a full rewrite of the previous overlay routines.
ViewProviderSketch:
- Major cleanup due to migration of functionalities to EditModeCoinManager
- Reduce public api of ViewProviderSketch due to refactor of DrawSketchHandler
- Major addition of documentation
- ShortcutListener implementation using new ViewProvider Attorney
- Gets a parameter handling nested class to handle all parameters (observer)
- Move rubberband to smart pointer
- Refactor selection and preselection into nested classes
- Removal of SEL_PARAMS macro. This macro was making the code unreadable as it "captured" a local stringstream that appeared unused. Substituted by local private member functions.
- Remove EditData
- Improve documentation
- Refactor Preselection struct to remove magical numbers
- Refactor Selection mechanism to remove hacks
ViewProviderSketchDrawSketchHandlerAttorney:
- new Attorney to limit access to ViewProviderSketch and reduce its public interface
- In order to enforce a certain degree of encapsulation and promote a not too tight coupling, while still allowing well
defined collaboration, DrawSketchHandler accesses ViewProviderSketch via this Attorney class.
-DrawSketchHandler has the responsibility of drawing edit temporal curves and markers necessary to enable visual feedback
to the user, as well as the UI interaction during such edits. This is its exclusive responsibility under the Single
Responsibility Principle.
- A plethora of speciliased handlers derive from DrawSketchHandler for each specialised editing (see for example all the
handlers for creation of new geometry). These derived classes do * not * have direct access to the
ViewProviderSketchDrawSketchHandlerAttorney. This is intentional to keep coupling under control. However, generic
functionality requiring access to the Attorney can be implemented in DrawSketchHandler and used from its derived classes
by virtue of the inheritance. This promotes a concentrating the coupling in a single point (and code reuse).
EditModeCoinManager:
- Refactor of updateConstraintColor
- Multifield - new struct to identify a single element in a multifield field per layer
- Move geometry management to delegate class EditModeCoinGeometryManager
- Remove refactored code that was never used in the original ViewProviderSketch.
CommandSketcherBSpline:
- EditModeCoinManager automatically tracks parameter change and triggers the necessary redraw, rendering an explicit redraw obsolete and unnecessary.
Rebase on top of master:
- Commits added to master to ViewProviderSketch applied to EditModeCoinManager.
- Memory leaks - wmayer
- Constraint Diameter Symbol - OpenBrain
- Minor bugfix to display angle constraints - syres
Architecture Description
=======================
* Encapsulation and collaboration - restricting friendship - reducing public interface
Summary:
- DrawSketchHandler to ViewProviderSketch friendship regulated via attorney.
- ShortcutListener to ViewProviderSketch friendship regulated via attorney.
- EditModeCoinManager (new class) to ViewProviderSketch friendship regulated via attorney.
- ViewProviderSketch public interface is heavily reduced.
In further detail:
While access from ViewProviderSketch to other classes is regulated via their public interface, DrawSketchHandler, ShortcutListener and EditCoinManager (new class) access
to ViewProviderSketch non-public interface via attorneys. Previously, it was an unrestricted access (friend classes). Now this interface is restricted and regulated via attorneys.
This increases the encapsulation of ViewProviderSketch, reduces the coupling between classes and promotes an ordered growth. This I call the "collaboration interface".
At the same time, ViewProviderSketch substantially reduces its public interface. Access from Command draw handlers (deriving from DrawSketchHandler) is intended to be restricted to
the functionality exposed by DrawSketchHandler to its derived classes. However, this is still only partly enforced to keep the refactoring within limits. A further refactoring of
DrawSketchHandler and derivatives is for future discussion.
* Complexity and delegation
Summary:
- Complexity of coin node management is dealt with by delegation to helper classes and specialised objects.
In further detail:
ViewProviderSketch is halved in terms of code size. Higher level ViewProviderSketch functions remain
* Automatic update of parameters - Parameter observer nested classes
Summary:
- ViewProviderSketch and CoinManager get their own observer nested classes to monitor the parameters relevant to them and automatically update on change.
The split enables that each class deals only with parameters within their own responsibilities, effectively isolating the specifics and decoupling the implementations. It is
more convenient as there is no need to leave edit mode to update parameters. It is more compact as it leverages core code.

================================================================================
GeoEnum static members are used in constexpr in GeoListId.
Previous code worked because the static members where inside the same translation unit.
This code:
1. Declares the static members to use them as constant expressions with the value
2. Definition of the static members (odr-used) shall not contain an initializer.
When new control points are created in a b-spline in a sketch, do not constrain
their weights to be equal to the first, unless they are already equal. This way
if we have unequal weights to begin with and OCC has computed the appropriate
weights so that the new spline is closer to the original, the weights are not
disturbed.
==============================
- Improve GeoList to support GeoElementId input
- Support VertexId to GeoElementId conversion
- GeoListModel gets separate getGeometry and getGeometryFacade naked pointers
- Sketcher: GeoList - make index mappings mutable
- Improve documentation
===================================================
This commit is an independent refactor of the identifications used at Sketcher level.
It introduces a new type "GeoElementId" as a combination of GeoId and PointPos.
It moves the Undefined GeoId, previous Constraint::GeoUndef to GeoEnum, together with all
other fixed values of GeoIds.
=================================================================
Common utility functions used by almost all Command classes were previous in Constraint.h.
Aside from providing a very bad intent, it created unnecessary header dependencies.
This commit separates these common functions into a new header, utils.h, which is then
used in all command classes where it is necessary.
