via their GUI metadata
Allows providers to create layer properties pages, giving us a nice
way to keep provider-specific logic out of the layer properties
classes.
* fix open form button not always enabled in relation reference widget
when the underlying model has more feature than what the model fetches by default (100),
the feature is not fetched yet when the combobox has its index changed
the new signal allows to be aware when the feature is ready to be used
mNmRelation and nNmRelationId represent the same QgsRelation instance
but it was possible to set them to different values.
Also added method nmRelation() to access the nmRelation directly.
When the backspace key is held down, points will be repeatedly
removed from streamed digitized sections, right up till the start
of the streaming section. Then the point removal will temporarily
pause until the user releases and re-holds down the backspace key.
This allows users to selectively remove portions of the geometry
captured with the streaming mode by holding down the undo key,
without risking accidental undo of non-streamed portions.
geometries
GREATLY speeds up rubber band creation for many geometries, resulting
in consequent speed ups to the move features tool, rotate features tool,
....
add an explicit log level getter/setter to QgsProcessingContext which
algorithms can use to determine an appropriate level of feedback
to push to users.
Initially the verbose log only triggers the full verbose output
of model executions (which is also used when running models through
the model designer), but the intention is that more algorithms
will fine tune their output based on the logging level.
qgis_process also gains a new --verbose switch to enable verbose
log output.
save changes
Regardless of the reason why the saving failed, a message about
invalid JSON was always shown... which is totally confusing for
users when a table has NO json fields or values (ﾉ｀Д´)ﾉ
like the user has made a selection, but they've only selected one
of the projection category headings and so when they click OK they
see no change.
Now instead we disable the OK button in this dialog whenever the
user has a non-crs list item selected.
which line symbol layer settings to show
Fixes fill symbol only related properties (like ring filters) show
for line symbols in some contexts.

This is useful when one wants to follow what exactly is happening
with map canvas rendering. We already have renderStarting() signal
when a job is started and mapCanvasRefreshed() signal when a job
has finished, but there was no notification if the pending job
got cancelled (for example because used moved/zoomed the map).
