Issue was caused by cycles setting scene frame which will update scene for
all the layers (not just visible ones) which confuses depsgraph making
objects which are needed as dependency are not really evaluated.
Made it so setting frame via scene.frame_set() which check whether update
need to be flushed to an invisible objects and do this if so.
Not ideal solution but seems to be safest at this point.
Issue was caused by curve orco calculation for rendering being freed
curve path and not calculating it back.
This left depsgraph in a state that it believed all the object data
is up to date but in fact some parts of data was freed by convert
blender.
Now made it so path is not being freed by render thread. This is
rather a workaround actually because ideally render thread need
to use copy-on-write here or at least use local cache here. But
current logic should be closer to what was happening in previous
release.
Issue was caused by undefined object update order and in some
cases NULL pointer will be de-referenced.
Added on-demand curve path calculation, just the same creepy call
of BKE_displist_make_curveTypes(). This violates DAG and might
end up in a difficult to troubleshoot race condition if there'll
be some issues with how dependencies are calculated in DAG, but
this is the easiest and safest way to solve the bug at this stage,
The issue was caused by the fact that sequencer used to cross-over effect
result with strips used for this effect, which is really stupid.
Now made it so strips which are used for effect inputs are not in the
render stack to be sure they would only be used by effect itself and
wouldn't be blended in any other way.
It is possible that objects from dupli-groups depends on objects which are
not in the dupli-group. We do need this objects to be evaluated as well on
visible changes, so all dependencies for objects from the dupli-group are
met. Unfortunately, we don't have parent relations on this state, so we're
to use DFS over the whole DAG to gather such dependencies.
This is probably not so bad since visible update is called really rarely.

Issue was caused by the change in FFmpeg options: some of them were
renamed, some moved to another class.
Made some tweaks to how options are passed to the FFmpeg which now
seems to be the same as ffmpeg.c.
Issue was caused by missing GLOBALHEADER flag set for audio stream.
Also made it so frame is getting filled with default, that's what
happening in ffmpeg.c.

This file crashes on loading with NULL pointer access to curve_cache:

The pdInitEffectors function was amalgamating the simple
collection of effector objects with an automatic precalculation for
curve guides and the like. This precalculation requires object data
that may not be available until the DAG has finished.
Since for DAG dependencies only the list of effectors is required,
added an argument to disable precalculation when collecting effectors.
Those derived meshes (used in Edit mode) were using simple sum of neighbor poly normals to get vertex normals,
while everywhere else in Blender we use weighted sum of such poly normals.

The "Cast Shadows" worked as expected, but it can cause problem in some cases.
For example, when using strand render, we need disabling only buffer shadows,
but the previous changes made that impossible. "Cast Shadows" should be added
as a newly created option.
This allows us to make materials that don't cast ray shadows.
Turning off this property can reduce the rendering time slightly.
Note: RNA path is changed to "use_cast_shadows" as well. The older
path "use_cast_buffer_shadows" still can be used as its alias, but
it will be removed after updating some addons.

FCurve Noise Modifer now has an extra float property which offsets the noise in time.
This is useful for creating follow through in procedurally animated noise.
For example, if you've used a noise modifier on a parent bone to add additional movement,
a quick and easy way to add overlapping motion is to create copies of that modifier on
its children, and then offset the time those curves play at. See this in action at:
