Includes project metadata in PDF exports, and supported image
based formats.
Image based metadata support depends on the format and the
Qt library's handling of each particular format (e.g. PNG
outputs are well supported).

Adds an option to include project metadata into SVG exports
generated from layouts, using the SVG RDF standard.

Allows retrieval of project metadata through QGIS expressions

This implements a new "import geotagged photos" algorithm
for processing. It allows selection of a folder which it
will scan for jpg files which have been geotagged and
creates a PointZ layer with the result, with attributes
for photo path, altitude, direction and timestamp.
Optionally the scan can be recursive and you can create
an optional table of photos which could not be read
or which were missing geotags.
The algorithm automatically sets the output table to
use an external resource widget to display the linked
photos in the attribute form.

Now it will accept arrays as well as string representations of arrays
Added a test

execution on generated layers after the algorithm (or parent
model) completes
This commit adds an interface for layer post-processing handlers
for execution following a processing algorithm operation.
Post-processing of a layer will ONLY occur if that layer is set
to be loaded into a QGIS project on algorithm completion.
Algorithms that wish to set post-processing steps for generated
layers should implement this interface in a separate class
(NOT the algorithm class itself!) and implement a method
to handle the layer post-processing.
This method always runs in the main thread and can be used to
setup renderers, editor widgets, metadata, etc for the given layer.
Fixes#17961
When INFO_FORMAT is not an image format there is no
need to make image WIDTH and HEIGHT mandatory.
2.x accepted that, 3.x raised an exception.
This is a partial fix: SRS is still mandatory because
fixing this would require a deeper refactoring and
I believe we can live with it, because SRS will be
required if filters are combined with geometry filters,
while passing a WIDTH/HEIGHT when we don't want an image
back is always useless.
A test was also added.
When an attribute table is set to a "Layer features" source, this
allows the underlying vector layer from which to source features
to be data defined.
(All existing table attributes (column settings) are left intact,
so setting a data defined table to a layer with different fields
will result in empty columns in the table.)

project dirtying for the lifetime of an object
Python code can then call:
project = QgsProject.instance()
with QgsProject.blockDirtying(project):
# do something
Use QgsProjectDirtyBlocker to prevent projects being marked as
dirty while creating a new project or while loading an existing
project -- avoids the titlebar temporarily showing the project
state as unsaved while it is being loaded.
This allows the project home path (which is used by the browser
to create the 'Project Home' item) to be set by users for a
project, instead of always matching the location where the project
is saved.
This allows users to set the project home to a folder which contains
data and other content, and is especially useful for organisations
where qgis projects are not stored in the root folder of a organisational
'project'.
Project home paths can also be set to relative paths, in which
case they will be relative to the project saved location.
The path can be set through the Project Properties dialog, or
by right-clicking on the Project Home browser item and
selecting 'set project home'
