When introduced in {rB61050f75b13e} this was actually working (meaning
it checked the Outliner OB_RESTRICT_RENDER flag and skipped the object if
desired).
Behavior has since then been commented in rBae6e9401abb7 and apparently
refactored out in rB2917df21adc8.
If checked, it seemed to be working (objects marked non-renderable in
the Outliner were pruned from the export), however unchecking that
option did not include them in the export.
Now it changed - for the worse if you like - in rBa95f86359673 which
made it so if "Renderable Objects" only is checked, it will still export
objects invisible in renders. So since we now have the non-functional
option with a broken/misleading default, it is better to just remove it
entirely.
In fact it has been superseeded by the "Visible Objects" option (this
does the same thing: depsgraph is evaluated in render mode) and as a
second step (and to make this even clearer) a choice whether
Render or Viewport evaluation is used can be added (just like the USD
exporter has). When that choice is explicit, it's also clear which
visibility actually matters.
This is breaking API usage, should be in release notes.

Blender was not configured to exit with non-zero return code on Python errors.
A bunch of tests worked around this but not all. This removes the need for such
workarounds.
There are two issues solved in this commit:
- Our Windows buildbot has slightly different floating point errors than
the Linux one, which meant a larger delta was required for float
comparisons.
- The test performs an export to a temporary Alembic file and
subsequently imports it. Deleting the temporary file was impossible on
Windows because it was still in use. This is now resolved by first
loading the default blend file before deleting the Alembic file.
The Alembic importer now works with local coordinates. Previously, the
importer converted transformations from Alembic to world coordinates
before processing them further; this processing often included
re-converting to local coordinates. This change made it possible to
remove some code that assumed that a child transform was only read after
its parent transform.
Blender's Alembic code follows the Maya convention, where in the zero
orientation the camera looks forward instead of down. This extra
rotation is now handled more consistently, and now also properly handles
children of cameras. This fixes T73269.
Unit tests were added to at least ensure that the importer and exporter
are compatible with each other, and that static and animated camera
transforms are handled in the same way.
This rename is to prepare for a future addition to the unit test file.
Currently it's named "import" and I will add an export test as well. The
rename is a separate commit to easily see the difference between the
rename and the addition of another test.
No functional changes.
