(e.g. parameters) when they are run in the "edit in-place" mode
This allows algorithms to dynamically adapt their behavior to make them compatible
with in-place mode. Previously, some useful algorithms could not be
run in-place because they alter a layer's structure (e.g. adding new
fields).
Now, these algorithms have a means to detect that they are being
run in-place and change their input parameters accordingly. E.g.
an algorithm which usually adds new fields to store calculated
values (such as "add xy fields to layer") could instead expose
field parameter choices to ask the user to pick from existing
fields in which to store the calculated values, thereby avoiding
the need to change the table structure and making them eligable
for running in-place mode.
Note that this needs to be handled algorithm-by-algorithm, it's
not automatic! It's just the raw api to allow this...
And add a Processing setting to allow these to be shown. When shown, they
are highlighted in red with a tooltip explaining that the algorithm
has known issues
processing options are changed
Make sure the algorithm dialogs use their own copy of algorithms,
instead of the copies owned by the processing registry. Opening
processing options triggers a full reload of providers, deleting
all existing algorithm instances from the registry first.
This is used in the algorithm's tooltip in the toolbox, and is intended
for single sentence description of the algorithm, e.g.
"Converts 2D features to 3D by sampling a DEM raster."
Convert grass algorithms to use short description for the
descriptive parts of their names, to cleanup the toolbox
and make it more uniform.
Brings the behaviour into line with the styling dock, where
the action is checkable and checked only when the toolbox
is open AND user visible (i.e. not hidden behind another tab). If
the toolbox is open but hidden, then hitting the Toolbox action
brings it to the front tab.
Otherwise it's often necessary to hit to Toolbox shortcut twice -
once to close a hidden toolbox tab, and a second time to open
and raise it.
Ensure that dialogs are always correctly deleted when appropriate.
Also, if an algorithm is running in a background task and hits
an error, we automatically re-show the algorithm dialog and the
associated log for debugging.
