Instead of terminating the handler, as mandated before this PR by ViewProviderSketch, ViewProviderSketch
delegates the action to DrawSketchHandler.
DrawSketchHandler implements by default this terminating behaviour, but allows to override it.
DrawSketchDefaultHandler (and all tools deriving from it) implement as default behaviour to cancel if
in initial state, otherwise to reset.

===============================================
Sets the full interface between the DrawSketchHandler and a tool widget available somewhere in the UI.
Signalling is as follows:
1. On activation of the tool, DrawSketchHandler notifies the tool widget.
2. The tool widget retrieves tool information necessary for representation (type of widget, visibility, ...)
3. When the tool widget has created an appropriate widget, it notifies back a widget change.
4. The tool receives the widget handler and can now configure and interact with the widget.
=================================================================
When in Sketcher edit mode, a tool button is activated, while the view has been changing to view of a different type, it segfaults.
This commit checks the pointer of the view to ensure correct type before activation, and refusing to activate if not of the correct type.
fixes#10809
===============================================
Revisiting all console calls:
- Using the Notification Framework when the user needs to be notified
- Turning them into DeveloperError/DeveloperWarnings when messages are intended only for developers
=======================================
Refactor:
- Substitute the use of variadic templates with parameter packs.
- Use recently incorporated external library "fmt" to handle printf like formating.
- Extensive cleaning of pragmas and unnecessary forward declarations.
- Parameter packs and libfmt provide a much stronger type checking now, so
conversions that are by standard implicit as bool to int need an explicit static_cast
to avoid compilation warnings.
Extension:
- Include a notifier field, so that the originator of the message can be provided. E.g. Document#DocumentObject
- Include a new type of message called CriticalMessage, this message is intended to have
special behaviour in the future. Namely, it will be used to notify forward compatilibity issues.
It will be used to substitute the current signal/slot mechanism.
- Include two new types of messages for user notifications (Notification and TranslatedNotification). This messages
will be use to convey UI notifications intended for the user (such as non-intrusive message about the usage of a tool). There
are two versions to mark whether the string provided as a message is already translated or not. When using the console system for
notifications, these notifications may originate from the App or the Gui. In the former, it is generally the case that the strings
of messages are not (yet) translated (but they can be marked with QT_TRANSLATE_NOOP). In the latter, often the messages to be provided
are already translated.
Python support for CriticalMessage, Notification and TranslatedNofification, including shortcuts:
Crt = FreeCAD.Console.PrintCritical
Ntf = FreeCAD.Console.PrintNotification
Tnf = FreeCAD.Console.PrintTranslatedNotification
==================================================
Naive 3 layer implementation to enable the removal of current rendering order.
Layers is conceived to be much more powerful, when combining User Layers, which
work at structural level (conceptually grouping of geometry by the user) and visual
layers (which control the representation of parts of User layers).
However, that implementation will take quite some time and effort to get it right.
This commit enables 3 layers:
1. Normal layer (legacy one)
2. Discontinuous layer (experimental layer which discontinuous edges)
3. Hidden layer (a normal layer which is hidden)
One geometry can be added to one and only one visual layer at a given time.
So this enables to hide geometry (by assigning it to the hidden layer), which is
useful for selection when lines are overlapping, acting as a work-around for the
rendering order. It also allows to rework the rendering order (without the user
being affected), which is also necessary for the final visual layers implementation.
==========================================
Extend ViewProviderGridExtension so that it is aware of the absolute direction of the XY plane on which the grid is to be drawn.
Fix the calculation of the cam origin.
Sketcher/Grid: fix algorithm computing the automatic grid spacing
Sketcher/Grid: forcefully redraw grid when one of its parameter is changed
Sketcher/Grid: always authorize user to change grid spacing, even if 'auto spacing' is enabled
Sketcher/Grid: apply a default factor of 10 for 'auto spacing' if number of subdivision is 1
===============================================
Removal of ViewProviderGridExtension properties:
-GridStyle
-GridSnap
Improvement of ViewProviderGridExtension API:
- color via App::Color
Toolbar grid command:
- Conversion of Snapping to edit parameter
- Snap gets a class enum to support future Snapping functionalities as edit parameter
Sketcher Settings:
- Removal of snap preference
Behaviour:
- ShowGrid, GridAuto, GridSize preferences do not change any existing VP. They apply to any newly created sketch.
- Do not limit grid to hardcoded values
Snap to grid:
- Code updated to use closestpoint functionality provided by the extension,
Several other fixes
==================================
- Move all grid specific code out of ViewProviderSketch and EditModeCoinManager.
- The code in made into a new extension in Part - ViewProviderGridExtension
- ViewProviderSketch starts deriving from this new extension
- ViewProviderSketch configures the extension according to its Grid preferences
- Grid code refactored to remove hardcoded sketcher preference parameters.
- ViewProviderGridExtension handles property name/type changes within its competence.
* QString::indexOf() is now marked as [[nodiscard]]
* QApplication::fontMetrics() is deprecated, use the constructor of QFontMetricsF
* fix -Wunused-result
* fix -Wunused-but-set-variable
