This way we allow animation system to make decisions based on which
context dependency graph is coming from, and whether it belongs to
an active edit window or not.
Saves quite a bit of CPU ticks per mesh update, giving measurable
speedup for file from T55228.
Memory usage goes up a it, most likely due to evaluated mesh having
more custom data layers than corresponding DM does.
Was caused by ec0756af6c, once again, we can't pass view layer,
need to pass index.
The sad part is that currently we don't have quick way to look up
view layer by index. Can do similar thing as we do for bones and
bases.
The depsgraph was always created within a fixed evaluation context. Passing
both risks the depsgraph and evaluation context not matching, and it
complicates the Python API where we'd have to expose both which is not so
easy to understand.
This also removes the global evaluation context in main, which assumed there
to be a single active scene and view layer.

This adds initial multi-object editing support.
- Selected objects are used when entering edit & pose modes.
- Selection & tools work on all objects however many tools need porting
See: T54641 for remaining tasks.
Indentation will be done separately.
See patch: D3101
For the performance we convert object bases list to an array
during view layer evaluation. This makes it possible to have
very cheap index-based base lookup.
The goal of this change is to get rid of base used for function
binding, and avoid scene datablock expansion at the depsgraph
construction time.
Do a direct update of object transform instead, without involving
manual trickery of recalc flag.
Shouldn't be functional changes as far as artists are concerned,
but will allow us to get rid of recalc flags in 2.8.
Thanks Bastien for review!
Previously it was done during depsgraph iteration, which is not good at all,
since after evaluation nobody should really modify how object was evaluated.
This is crucial bit since batch cache is stored in the evaluated object,
meaning we can't tag it's hatch cache dirty from the notifier system.
Not easily at least. Better to leave this job to depsgraph, it knows
all the copies of data.
This makes code closer to id_override/assent-engine ones, which
introduce a new type of linked data, and hence reserve
ID_IS_LINKED_DATABLOCK to real linked datablocks.
Before it was a compile time option which was not very easy to use or test. Now
the project is getting more mature, so very soon we will be able to call for a
public tests of limited features.
The copy-on-write (which includes animation, modifiers) is enabled using
--enable-copy-on-write command line argument.
- NOCHECK -> ALL
- ALL -> MAYBE_ALL
Where 'MAYBE_ALL' checks to see if the mesh has changed.
This is clearer that `BKE_MESH_BATCH_DIRTY_ALL` is dirty and
going to be updated without any guess-work.
