Root of the issue here was that two stupid modifiers could create named
vgroup CD layers (vgroup editing ones... shame on me :") ).
Fix that, and added some versionning code to also fix 'corrupted' blend
files created by those so far.
There is no more point of keep those around. ES20 may need special case
when/if we dabble with it again. Meanwhile no point on polluting the
code with this.
(ghost still has reference for the PROFILE, but that's reasonable)
Nothing terribly exciting, just a hackish implementation of solid mode CDDM
drawing for cases when we are building with core profile.
The goal is to be able to see SOMETHING with new OpenGL for thew guys who
tests alembic and friends in blender2.8 branch. This is a temporary solution,
the whole drawing will be reworked. Limited to hardcoded material and lighting.
Selection outline color is also hardcoded because of lack of glColor() in the
core profile.
After this commit there is no big stoppers from stop worrying about legacy
OpenGL, so we can go core profile as the only way for Blender.
While some areas will become broken after that, we'd better just fix them
after that and for now just focus on more important design work.
Sanitize a bit how cache path is handled by fluidsim (there is much more
to be done here though :( ), and forbid empty path (we reset to default
path relative to current .blend file in case it's empty).
If people really, really want to use current OS-wise directory, they can at
least use '.' as path. ;)
These bits became obsolete with the new layer system, so we can
simplify some code around them or avoid existing workarounds which
were trying to keep things working for them.
There are still work needed to be done for on_visible_change to
avoid unnecessary updates, but that can also happen later.
This slightly changes SDef behavior, by now respecting object transforms
at bind time, thus not requiring the objects to be aligned in their
respective local spaces, but instead using world space.

User Commit Log
---------------
* New Layer and Collection system to replace render layers and viewport layers.
* A layer is a set of collections of objects (and their drawing options) required for specific tasks.
* A collection is a set of objects, equivalent of the old layers in Blender. A collection can be shared across multiple layers.
* All Scenes have a master collection that all other collections are children of.
* New collection "context" tab (in Properties Editor)
* New temporary viewport "collections" panel to control per-collection
visibility
Missing User Features
---------------------
* Collection "Filter"
Option to add objects based on their names
* Collection Manager operators
The existing buttons are placeholders
* Collection Manager drawing
The editor main region is empty
* Collection Override
* Per-Collection engine settings
This will come as a separate commit, as part of the clay-engine branch
Dev Commit Log
--------------
* New DNA file (DNA_layer_types.h) with the new structs
We are replacing Base by a new extended Base while keeping it backward
compatible with some legacy settings (i.e., lay, flag_legacy).
Renamed all Base to BaseLegacy to make it clear the areas of code that
still need to be converted
Note: manual changes were required on - deg_builder_nodes.h, rna_object.c, KX_Light.cpp
* Unittesting for main syncronization requirements
- read, write, add/copy/remove objects, copy scene, collection
link/unlinking, context)
* New Editor: Collection Manager
Based on patch by Julian Eisel
This is extracted from the layer-manager branch. With the following changes:
- Renamed references of layer manager to collections manager
- I doesn't include the editors/space_collections/ draw and util files
- The drawing code itself will be implemented separately by Julian
* Base / Object:
A little note about them. Original Blender code would try to keep them
in sync through the code, juggling flags back and forth. This will now
be handled by Depsgraph, keeping Object and Bases more separated
throughout the non-rendering code.
Scene.base is being cleared in doversion, and the old viewport drawing
code was poorly converted to use the new bases while the new viewport
code doesn't get merged and replace the old one.

The title says it all actually. Use BLI task to loop over vertices
and distort their locations. Gives 2x FPS increase in a file with
just time-dependent displace modifier on my desktop.
This version will give less spin locks and now well-tested by render engines.
This should reduce amount of threading overhead when having multiple objects
with displace modifier enabled.
In the future this will also help us threading the modifier.
There are more modifiers which could benefit from this, but let's first
investigate the new behavior with one of them.
Better to have clear way to tell whether flag is parameter for
BKE_library_foreach_ID_link(), parameter for its callback function, or
return value from this callback function.
Checking only whether mverts is same as base mesh one is not enough in
all cases, some modifiers (deform ones) can only generate new mvert
data, while keeping others from original mesh.
Now checking both mvert or medge, hopefully this will be enough to catch
all problematic cases this time.
Thanks @gaia for finding that problem. :)
