Allows processing models to be stored inside QGIS project files,
so that opening the project makes that model available.
Some models are so intrinsically linked to the logic inside
a particular project that they have no meaning (or are totally
broken) outside of that project (e.g. models which rely
on the presence of particular map layers, relations, etc)
This change allows these models to be stored inside that project,
avoid cluttering up the "global" model provider with models
which make no sense, and making it easier to distribute a single
project with these models included.
Models are stored inside projects by clicking the new "embed
in project" button in the modeler dialog toolbar. Models can be
removed from a project from the model's right click menu in the
toolbox.
This is supported by the toolbox now, so relax the requirement
that all models have a compulsory group name. If no group is set,
the model is shown directly under the Models node in the toolbox.
Also switch a warning from message box to message bar
Because there's some deep underlying issue which causes the dock
layouts to get corrupted in certain circumstances, avoid the
issue entirely by moving construction of the docks out of
the .ui file and instead do it all manually via Python code.
Fixes#16428, #19068
This is used in the algorithm's tooltip in the toolbox, and is intended
for single sentence description of the algorithm, e.g.
"Converts 2D features to 3D by sampling a DEM raster."
Convert grass algorithms to use short description for the
descriptive parts of their names, to cleanup the toolbox
and make it more uniform.
...to help clarify for users what the different input types mean.
Fixes#17671, which is a result of unclear distinction between
the uses of vector features vs vector layer inputs.

Ensure that dialogs are always correctly deleted when appropriate.
Also, if an algorithm is running in a background task and hits
an error, we automatically re-show the algorithm dialog and the
associated log for debugging.
Fixes#16858
Adds a new QGIS processing provider for 3d algorithms, available
only when QGIS is built WITH_3D
Currently includes only a single algorithm for tesselating geometries,
which exposes the functionality of QgsTesselator to processing.
Like the native c++ algorithm provider, algorithms in the 3d
provider are transparently merged with the other QGIS providers
(i.e. they aren't separated into their own group)
While the toolbar buttons were shown in the correct size, the
actual icon image in the buttons was not correctly scaling to
match the button size.
Hardcoding the svg icons in the py file seems to be the only
way to avoid this.
The dialogs are parented to the main window, which means sip
transfers the ownership to the main window - and they are
never deleted as a result. This results in various error
messages caused by the widgets hanging around forever
and listening out for various signals they are connected to.
