No major API change here, only in the outliner restriction column
variables (e.g., show_restrict_column_selectable > show_restrict_column_select).
* Get rid of _INSTANCE (introduced on b1af682001).
* Differentiate (everywhere but the API) between HIDE (temporary) and VIEWPORT (global).
* Use the expected icon for restrict viewport (same as objects and modifiers).
* selectable > select
See T61578 for discussions and mockups.
Visibility Options
==================
We are adding more granular control over restriction columns in the outliner,
exposing "indirect only" and "holdout" as options, and change the way
users enable/disable collections in a viewlayer.
We also rename the object viewport restriction to hide instance.
So the options we have are:
Collection
----------
* Render Visibility
* Instance Visibility
* Selectable
(View) Layer Collection
-----------------------
* Enable
* Holdout
* Indirect Only
* Viewport
Shortcuts
=========
Isolate Collection
------------------
* Ctr + click isolates the collection.
It turns all its parents and children "visible", and all the other
collections "invisible".
If ALL the collections were already properly set, we re-set the
collections to their default value.
Set Collection Inside Collections and Objects
---------------------------------------------
* Shift + click: Set/unset inside collections and objects.
We only set objects values as well when we are in View Layer mode and
(obviously) when the objects have a matching property.
Icons
=====
Little reminder that we will need better icons for holdout, indirect only, and
probably instanced (nothing wrong with the current, but it differs from
the proposal when it is turned off).
Also, we need to decide where do we want the modifier/bones/... icons to
be (in which column) and ideally make sure their icons match the ones we
use for collections/objects.
At the moment those are using the screen icon, which is not being used
by collections.

This should not use the original index as a unique instance index, with for
example an array modifier the same original index may be used multiple times.
Convention was not to but after discussion on 918941483f we agree its
best to change the convention.
Names now mostly follow RNA.
Some exceptions:
- Use 'nodetrees' instead of 'nodegroups'
since the struct is called NodeTree.
- Use 'gpencils' instead of 'grease_pencil'
since 'gpencil' is a common abbreviation in the C code.
Other exceptions:
- Leave 'wm' as it's a list of one.
- Leave 'ipo' as is for versioning.
Made it so that generated coordinate is always calculated.
Ideally, it will only be done depending on a current shading,
but code is quite deep, and doing smarter thing here will end
up in way bigger refactor.
First, make things working, and then make them fast if they
pop up in a profiles.
It is supposed to be already evaluated. If for some reason it's not
doing such direct evaluation will not be reliable anyway (indirect
dependencies for example).
This fixes an assert part of T61431.
BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
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.
See P901 for script to perform these edits.
Some features are incompatible with multithreading and reliable evaluation
of dependencies. We are now removing them as part of a bigger cleanup to
fix bugs in keyframing and invalid animation evaluations.
* Dupliframes have been removed. This was a hack added before there were
more powerful features like the array modifier.
* Slow parent has been removed, never worked in 2.8. It was always
unreliable for use in production due to depending on whatever frame was
previously evaluated, which was not always the previous frame.
* Particle instanced objects used to have their transform evaluated at
the particle time. Now it always gets the current time transform.
* Boids can no longer do predictive avoidance of force field objects,
but still for other particles.

This commit makes it so curve path parent solving accepts an explicit
arguments for both time and curve speed flag, making it so we don't
have to mock around with scene's frame.
One unfortunate issue still is that if the instancing object is used
for something else, we might be running into a threading conflict.
Possible solution would be to create a temp copy of an object, but
then it will be an issue of preventing drivers from modifying other
datablocks.
At least the original issue is fixed now, and things behave same as
in older Blender version. Additionally, the global variable which
was defining curve speed flag behavior is gone now!
Terms get/set don't make much sense when casting values.
Name macros so the conversion is obvious,
use common prefix for easier completion.
- GET_INT_FROM_POINTER -> POINTER_AS_INT
- SET_INT_IN_POINTER -> POINTER_FROM_INT
- GET_UINT_FROM_POINTER -> POINTER_AS_UINT
- SET_UINT_IN_POINTER -> POINTER_FROM_UINT
There is now a manual refresh button on the panel to update the list
of objects in case it changes, and it also gets refreshed when changing
the collection or toggling the use count option.
This is a bit more manual but the previous code of refreshing the
list while evaluating the depsgraph was unreliable.
This also fixes it to take properly take into account visibility, and
to work with linked collections for which index writing was missing.
The function definitions still reside in DerivedMesh.c. Once we're done
porting all the DerivedMesh use to Mesh, we'll move the still-relevant
functions to mesh_runtime.c. This move is now cumbersome due to shared
statically-declared utility functions in DerivedMesh.c
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.
OVERVIEW
* In 2.7 terminology, all layers and groups are now collection datablocks.
* These collections are nestable, linkable, instanceable, overrideable, ..
which opens up new ways to set up scenes and link + override data.
* Viewport/render visibility and selectability are now a part of the collection
and shared across all view layers and linkable.
* View layers define which subset of the scene collection hierarchy is excluded
for each. For many workflows one view layer can be used, these are more of an
advanced feature now.
OUTLINER
* The outliner now has a "View Layer" display mode instead of "Collections",
which can display the collections and/or objects in the view layer.
* In this display mode, collections can be excluded with the right click menu.
These will then be greyed out and their objects will be excluded.
* To view collections not linked to any scene, the "Blender File" display mode
can be used, with the new filtering option to just see Colleciton datablocks.
* The outliner right click menus for collections and objects were reorganized.
* Drag and drop still needs to be improved. Like before, dragging the icon or
text gives different results, we'll unify this later.
LINKING AND OVERRIDES
* Collections can now be linked into the scene without creating an instance,
with the link/append operator or from the collections view in the outliner.
* Collections can get static overrides with the right click menu in the outliner,
but this is rather unreliable and not clearly communicated at the moment.
* We still need to improve the make override operator to turn collection instances
into collections with overrides directly in the scene.
PERFORMANCE
* We tried to make performance not worse than before and improve it in some
cases. The main thing that's still a bit slower is multiple scenes, we have to
change the layer syncing to only updated affected scenes.
* Collections keep a list of their parent collections for faster incremental
updates in syncing and caching.
* View layer bases are now in a object -> base hash to avoid quadratic time
lookups internally and in API functions like visible_get().
VERSIONING
* Compatibility with 2.7 files should be improved due to the new visibility
controls. Of course users may not want to set up their scenes differently
now to avoid having separate layers and groups.
* Compatibility with 2.8 is mostly there, and was tested on Eevee demo and Hero
files. There's a few things which are know to be not quite compatible, like
nested layer collections inside groups.
* The versioning code for 2.8 files is quite complicated, and isolated behind
#ifdef so it can be removed at the end of the release cycle.
KNOWN ISSUES
* The G-key group operators in the 3D viewport were left mostly as is, they
need to be modified still to fit better.
* Same for the groups panel in the object properties. This needs to be updated
still, or perhaps replaced by something better.
* Collections must all have a unique name. Less restrictive namespacing is to
be done later, we'll have to see how important this is as all objects within
the collections must also have a unique name anyway.
* Full scene copy and delete scene are exactly doing the right thing yet.
