These may represent additional layers such as layers which
are not included in the map layer registry, or paths to
layers which have not yet been loaded into QGIS.
Now all classes and members are either exposed to bindings or marked
as "not available in Python bindings" in the docs.
Drop test thresholds to 0. Now it should be much easier to determine
what missing members have been added which are causing test
failures.
Rationale:
- there was a lot of large objects passed by value, so potentially
there's a speed bump from this
- even for implicitly shared classes like QString/QList there's still
a (small) cost for copying the objects when there's no reason to
- it's the right thing to do!
is not applied
This could also have been fixed by changing from the activated
signal to currentIndexChanged for the indexChanged connection,
but it looks like activated was intentionally used here.
