This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.

The problem here was that when a render result is allocated, the standard render passes are added according to the
pass bitfield. Then, when the render engine sets the result, it adds the additional passes which are then merged
into the main render result.
However, when using Save Buffers, the EXR is created before the actual render starts, so it's missing all those
additional passes.
To fix that, we need to query the render engine for a list of additional passes so they can be added before the EXR
is created. Luckily, there already is a function to do that for the node editor.
The same needs to be done when the EXR is loaded back.
Due to how that is implemented though (Render API calls into engine, engine calls back for each pass), if we have
multiple places that call this function there needs to be a way to tell which one the call came from in the pass
registration callback. Therefore, the original caller now provides a callback that is called for each pass.
Terms get/set don't make much sense when casting values.
Name macros so the conversion is obvious,
use common prefix for easier completion.

Seems to be only related on linked nature of particles.
This is caused by some conflicting optimization done for viewport, which
does not do particles re-calculation if they do not depend on time
(which is crucial for big layout scene grass fields) and particle render
setting switch which was relying on fact that render pipeline will do
particle update via time dependency.
Now we extent an old workaround for invisible objects, which now also
deals with particles in the same way as old dependency graph was dealing
with this: tag object data for update if there is particle system.
There shouldn't be any speed difference between old and new depsgraph,
since tagging was already needed and was happening.
In Blender 2.8 such things should be easier to deal with since the whole
depsgraph is to be evaluated for render engine anyway.
In preparation of the removal of blender internal render we
moved the vectorblur code that was placed in the render package
(legacy) to the compositor. The compositor is only using this
code even the blender internal renderer did not use the code at
all.
- Metadata handling is now separate from `ImBuf *`, allowing it to be
used with a generic `IDProperty *`.
- Merged `IMB_metadata_add_field()` and `IMB_metadata_change_field()`
into a more robust `IMB_metadata_set_field()`. This new function
doesn't return any status (it now always succeeds, and the previously
existing return value was never checked anyway).
- Removed `IMB_metadata_del_field()` as it was never actually used
anywhere.
- Use `IMB_metadata_ensure()` instead of having
`IMB_metadata_set_field()` create the containing `IDProperty` for
you.
- Deduplicated function declarations, moved `intern/IMB_metadata.h` out
of `intern/`. Note that this does mean that we have some extra
`#include "IMB_metadata.h"` lines now, as the metadata functions are
no longer declared in `IMB_imbuf.h`.
- Deduplicated function declarations, all metadata-related declarations
are now in imbuf/IMB_metadata.h.

It seems to be useful still in cases where the particle are distributed in
a particular order or pattern, to colorize them along with that. This isn't
really well defined, but might as well avoid breaking backwards compatibility
for now.
The reason it appeared working was due to left-over debug code to force
time dependency.
Real fix seems to include force tagging objects used by duplication,
similar to what we do for some other modifiers already.
