Adds an interface for classes which provider custom
handlers for features rendered as part of a map render job.
QgsRenderedFeatureHandlerInterface objects are registered
in the QgsMapSettings objects used to construct map render
jobs. During the rendering operation, the handleRenderedFeature()
method will be called once for every rendered feature, allowing
the handler to perform some custom task based on the provided
information.
They can be used for custom tasks which operate on a set of
rendered features, such as creating spatial indexes of the
location and rendered symbology bounding box of all features
rendered on a map.
This new setting, "Simplify geometries to reduce output file size",
is exposed in the SVG or PDF export settings dialogs shown when
exporting a layout/atlas/report to PDF or SVG.
If checked (the new default), geometries will be simplified while exporting
layouts in order to remove any redundant vertices which are not
discernably different at the export DPI. (e.g. if export DPI is 300 dpi,
vertices less then 1/600 inch different from each other will be removed).
This avoids exporting ALL geometry vertices during PDF/SVG export,
which can result in a ridiculously complex and large export file size.
Aside from the file size issues, it also causes problems when trying
to load these outputs into other applications, e.g. Inkscape, which
chokes on the huge number of vertices and grinds to a crawl.

QgsMapSettings object
If specified (they default to off), these simplification settings
will override any layer-specific simplification settings, and
provide a way for specifying a global simplication to apply
to vector layers while exporting maps.
instead of fake ones
Gives these buttons the full power of the usual QgsSymbolButton,
including copy/paste symbols, color/opacity changes, etc. Plus,
some nice additional interface consistency!
and add handleMimeDataV2 method which returns a bool
This allows custom drop handlers to indicate that they've fully
handled dropped mime data, and that no further processing should
be done on the mime data
coordinate operations when selecting operations
This is the closest equivalent for the existing "hide deprecated"
checkbox which is available in proj < 6 builds.
Requires Proj >= 6.2
