There are two unnecessary Layer warnings:
1. A 'might break' warning when deleting an object nested in a layer.
2. An 'out of scope' warning for objects also nested in f.e. a Std_Part.
To avoid them the Group property type was changed to `App::PropertyLinkListHidden`.
Fixes#14312.
The `new _get_shapes` function could return the original object shape. This caused a problem if `sh.reverse()` executed.
Note that the file in the linked issue does not produce the error as it does not contain a shape with a negative volume.
Discussion: #13657.
This PR adds the ShapeAppearance view property to Draft Layers.
The DefaultShapeColor is used for the DiffuseColor of the ShapeAppearance material. Other material properties are not based on the preferences when a layer is created.
The old ShapeColor and Transparency properties remain (ShapeColor as a hidden property) and are kept in synch with the ShapeAppearance. This is consistent with how ShapeAppearance is implemented in Core.
The gui_layers.py and make_layer.py files do not have to be changed. They manipulate the vobj via the mentioned old properties.
Fixes#14242.
In the current dev fusing an empty shape with a face or solid no longer works (probably introduced with #14169). The reason for starting with an empty shape was the assumption that the end result would then always have a default placement. But that is only correct if multiple objects are fused.
In the new version of the code fusing no longer starts with an empty shape. The default placement issue is solved by always returning a compound.
Additionally the value for the Area property is now taken after offsetting and fusing the faces.
Edges longer than ca. 10m are considered 'crazy' in the TD Workbench. Hatch patterns are also checked. As a workaround some intermediate scaling is applied.
Addionally: `transformShape` instead of `transformGeometry`. The latter results in B-splines.
The proposed code fixes the following issues:
1. There is no check if the target object itself has a property that matches the label type.
2. If a subelement is selected that does not have the label type property, the value from the main object is displayed instead.
3. The default text is an empty string.
Example:
Currently If you select a vertex of a wire, and select "Length" as the label type, you will get the length of the wire. With the new code the text will then be "Length not available for (sub)object".
Forum topic (issue #1):

These messages were perhaps originally intended as a debuggin aid but now add clutter to the output panes. Remaining messges are mostly the result of methods to display attributes of an object (which one could call from the Python console) or actually provide some information which would not be obvious from the circumstances

Additionally:
* Fixed offset and extrusion for non-planar faces.
* Improved the addSubobjects function,
* Cleaned up the code a little bit.
Since Py3.11 the methods names __setstate__ and __getstate__ conflict with the method names added to the object class.
Thus rename them to 'loads' and 'dumps'
* Add offset options to Draft PathArray
Allows user to specify a starting and ending offset to items in Draft PathArrays.
* [Draft] path array offset
