polygons
Options are:
- 'yes': allow placing outside the polygon if needed
- 'no': don't allow outside placements
- 'force': only ever put this label outside the polygon
outside of polygon features when required
When a label can't be placed inside the polygon and this option is checked,
then it will be automatically placed at a nicely selected location
just outside of the polygon

Allows users to override the symbol patch size for individual legend
nodes, by double clicking the node
Width and height can be individually overridden, with the node falling
back to the default width or height when the override isn't set.

- filtering of input layers by expressions and min/max zoom level
- custom layer names in the output
- writing of custom metadata for MBTiles output
- auto-calculate output extent (instead of defaulting to the whole world's extent)
- passing transform context to the encoder
Introduce a renderer for 1D mesh edges that can vary width over the line. The line can also have different color based on the actual dataset value on the line's point.

QgsScopedRenderContextPainterSwap: allows for temporarily swapping
the destination painter object for a QgsRenderContext for the lifetime
of the object
QgsScopedRenderContextScaleToMm: temporarily rescales a render context
destination painter device to use millimeter based units for the lifetime
of the object
QgsScopedRenderContextScaleToPixels: temporarily rescales a render
context (which has been scaled to millimeter based units) back
to pixel based units, for the lifetime of the object
- alias WKT_2018* to new WKT_2019* values, since the spec is actually
2019, not 2018
- add WKT_PREFERRED value which currently aliases to WKT2_2019, but
can be changed if/when future bumps to the WKT spec happen
- add WKT_PREFERRED_GDAL which should be used whenever a CRS is
exported to WKT for use with GDAL API. Aliases to WKT2_2019 currently,
but can be changed if/when a new spec is released and GDAL supports it
Initial work... Currently supporting output to a directory based on XYZ template, using Mapbox vector tiles encoding.
New classes:
- QgsVectorTileMVTEncoder - low-level class that operates on a single tile, converts vector features to raw tile byte array, for internal use
- QgsVectorTileWriter - higher level class that manages generation of multiple tiles, for use by clients
- QgsVectorTileMVTUtils - assorted helper functions for MVT encoding/decoding
Until now, if a plugin adds a custom data item provider that adds
a root item to the browser model, the new root data item would not
get added and a restart of QGIS was necessary.
This algorithm allows useres to setup multiple conditions (via qgis expressions),
which cause their corresponding branch of the model to be run or skipped
depending on the result of the expression evaluation.
