Adds label distance factor spinbox to Point Displacement symbology
window. Calculates label distance based on the current symbology
diagonal instead of a general maximum diagonal.
Replaces the hard coded distance "symbolDiagonal/2.0" with
"symbolDiagonal*mLabelDistanceFactor", where mLabelDistanceFactor is set
to the spinbox value.
It's an old feature request (Point displacement labels adjustable
offsets "https://issues.qgis.org/issues/5945").
The centroid of the geometry is used for the point parameter value.
This makes it easier to write expressions for the value of point
parameters, since all the QGIS expression functions for working
with geometry types return QgsGeometry value themselves (e.g.
make_point, centroid, ...). In this case it's much nicer to
allow expression values like `make_point(3,4)` within a precalculated
expression based value in a Processing model.
The CRS parameter is considered as mandatory in GetFeatureInfo even if the FILTER parameter is used without I and J parameters.
To fix it, set a fake CRS in the parameter when I/J and X/Y parameters are not defined and FILTER parameter is defined.
In QGIS Server 2.* the WMS GetPrint request could genrate JPEG image. QGIS Server 3.4 has lost this capabilities.
```
<ServiceExceptionReport xmlns="http://www.opengis.net/ogc" version="1.3.0" capture-installed="true">
<ServiceException code="InvalidFormat">
Output format jpg is not supported by the GetPrint request
</ServiceException>
</ServiceExceptionReport>
```
To fix this regression, it is necessary to accept JPEG output format.
And to avoid this regression to come back, the QGIS Server tests has been updated to accept jpg image test.
This algorithm creates a polygon layer containing the extent
of a print layout map item, with attributes specifying the map
size (in layout units), scale and rotatation.
The main use case is when you want to create an advanced overview
indicator and the inbuilt layout tools to do this don't suffice.

Turns out there is NO reliable way to create a proxy model
which adds new rows to a model, so just bite the bullet and
do it in the underlying model (yuck)
[feature] [mesh] #20731 add option to format time in mesh layer
There is new settings dialog that can be opened by button next to time slider. User can set reference time and time format (e.g. 2019-03-21 22:01:11).
This adds a new parameter type specifically for map scales,
QgsProcessingParameterScale. The values are evaluated using
self.parameterAsDouble, which returns the map scale
denominator (matching the standard in other parts of the
QGIS API).
Scale parameters are displayed to users using the standard
QgsScaleWidget, which includes the combo box of predefined
scales and a shortcut button to match the current map scale.
