These allow plugins to extend the "Open Project" dialog by adding in support
for new file filters, which appear in the formats drop down list alongside
the existing "QGS Projects" entry.
Custom project open handlers then get first chance at loading project files.
This allows plugins to extend QGIS support by adding integrated support for
opening projects from non QGS/QGZ formats, e.g. allowing users to open
ArcGIS MXD documents or MapInfo WOR Workspaces direct from the project open
dialog.
These non-native projects are also added to the recent projects list and
welcome screen, giving them a truly first-class experience within QGIS.

This new renderer draws contour lines that are calculated on the fly
from the source raster band. It is possible to set interval of contour
lines and symbol used for drawing.
In addition there is support for "index contours" - contour lines
with higher interval, typically drawn with a wider line symbol.
If we generate contour lines on input raster block with the same size as our
output raster block, the generated lines would contain too much detail.
This detail can be reduced by the "downscale" factor - this will request
lower resolution of the source raster.
Motivation :
Move the QgsRasterLayerProperties class to the GUI API.
So, this class could be used using the QGIS API, notably for standalone applications.
The instance of this class was dependent, since QGIS 3.8, from the QgisApp instance, when calling the askUserForDatumTransform(). As this method, defines a title and only call QgsDatumTransformDialog::run() method from the gui API, this PR purpose to :
* [FEATURE] Selective masking
Advanced rendering feature that allows the definition of 'masks' areas around labels or with a new typ of symbol layer. These masks will "un-draw" symbol layers of other layers underneath.
It modifies the rendering process by adding an optional second pass.
to handle creation of parameter definition widgets
Previously, these configuration widgets were all hardcoded into the Python modeler
dialog. This prevented 3rd party, plugin provided, parameters from ever being full
first class citizens in QGIS, as there was no way to allow their use as inputs to
user created models to be customised.
Now, the registry is responsible for creating the configuration widget, allowing
for 3rd party parameter types to provide their own customised configuration
widgets.
