First pass, some issues remain
|

It is basically brute force volume scattering within the mesh, but part
of the SSS code for faster performance. The main difference with actual
volume scattering is that we assume the boundaries are diffuse and that
all lighting is coming through this boundary from outside the volume.
This gives much more accurate results for thin features and low density.
Some challenges remain however:
* Significantly more noisy than BSSRDF. Adding Dwivedi sampling may help
here, but it's unclear still how much it helps in real world cases.
* Due to this being a volumetric method, geometry like eyes or mouth can
darken the skin on the outside. We may be able to reduce this effect,
or users can compensate for it by reducing the scattering radius in
such areas.
* Sharp corners are quite bright. This matches actual volume rendering
and results in some other renderers, but maybe not so much real world
objects.

We've got quite comprehensive BMesh based implementation, which is way easier
for maintenance than abandoned Carve library.
After all the time BMesh implementation was working on the same level of
limitations about manifold meshes and touching edges than Carve. Is better
to focus on maintaining one boolean implementation now.

- Read-only access can often use EvaluationContext.object_mode
- Write access to go to WorkSpace.object_mode.
- Some TODO's remain (marked as "TODO/OBMODE")
- Add-ons will need updating
(context.active_object.mode -> context.workspace.object_mode)
- There will be small/medium issues that still need resolving
this does work on a basic level though.

Add a enum headers to DNA, to be included in other headers
so function signatures can use enums for better type safety.
Add DNA_*_enums.h matching DNA_*.types.h as needed.

This adds midlevel and object/world space for displacement, and a
vector displacement node with tangent/object/world space, midlevel
and scale.
Note that tangent space vector displacement still is not exactly
compatible with maps created by other software, this will require
changes to the tangent computation.

General idea of the fix: skip the whole draw manager callback madness which
was used to tag object's engine specific data as dirty. Use generic recalc
flag in ObjectEngineData structure instead. This gives us the following
benefits;
- Sovles mentioned bug report.
- Avoids whole interface lookup for opened viewports for EVERY changed ID.
- Fixes missing updates when viewport is temporarily invisible.

Main idea is to make specific engine types be a subclass of generic
ObjectEngineData structure.
This required following changes:
- Have extra size argument to engine data allocation function.
Not sure whether there is less error-prone way of doing this.
- Add init() callback to engine data allocation function.
Additionally, added some extra checks to Eevee's engine data getters, so we do
not silently cast lamp data to lightprobe data.

USER_ZBUF_ORBIT -> USER_DEPTH_NAVIGATE
The name didn't make sense since it's used for all view navigation.
Also rename USER_ZBUF_CURSOR -> USER_DEPTH_CURSOR since zbuf
is an internal detail.

Move timer and tip out of button code,
now the only requests a tooltip,
passing a creation callback to run.
Needed for manipulators in 2.8,
also helps de-duplicate logic - since we never want
multiple tool-tips showing at once.

This was not implemented yet. So it's a bit pointless to have all this
placeholder code around without any functionality coming out of it.

This works for grid and cubemaps.
The intensity is baked into the map itself. Thus you need to refresh/rebake the probe to see the changes.

This was introduced to the outliner when we had no User Preference
window back in 2.5x. Right now it makes no sense to keep this around.
But how about addon user preferences:
* They belong in the user preference window under the addon.
How about the user preferences themselves:
* You find them in the user preference window.
And templates?
* Why are they here in the first place?
After talking to Pablo Vazquez (who in turn poked Sergey Sharybin) we found
it reasonable to get rid of this. If it turns out that we were wrong we
revert this.
As for leaving this exposed as a debug option (as suggested on IRC) I would say
no, please. This end up polluting the code and never cleaned up in the end.
(this was specific talking about templates).
Technical note: I left the functions in outliner still hanging around.
While I used UNUSED_FUNCTION for one of them, for the other one I had to use:
`#if 0` because the function was calling itself, which would fail to build if
I used UNUSED_FUNCTION.

We have different ways of explore the scene objects, namely View Layer and
Collections. This change let us focus on compositing elements only such as:
* View Layers
** Collections
** Render Passes
* Freestyle
* Grease Pencil?
Not included in this commit is an option to handle filtering of
collections passes, ... Not sure if we would like, though.
Since they are all properly nested under a "Collections" / "Passes"
parent.

User notes:
The outliner so far was a great system to handle the object oriented workflow
we had in Blender prior to 2.8. However with the introduction of collections
the bloated ammount of data we were exposed at a given time was eventually
getting on the way of fully utilizing the outliner to manage collections and
their objects.
We hope that with this filtering system the user can put together the outliner
with whichever options he or she seem fit for a given task.
Features:
* Collection filter: In case users are only focused on objects.
* Object filter: Allow users to focus on collections only.
* (Object) content filter: Modifiers, mesh, contrainst, materials, ...
* (Object) children filter: Hide object children [1].
* Object State (visible, active, selected).
* Compact header: hide search options under a search toggle.
* Preserve scrolling position before/after filtering [2].
[1] - Note we still need to be able to tell if a children of an object is in a
collection, or if the parent object is the only one in the collection.
This in fact was one of the first motivations for this patch. But it is to
be addressed separately now that we can at least hide children away.
[2] - We look at the top-most collection in the outliner, and try to find it again
after the filtering and make sure it is in the same position as before.
This works nice now. But to work REALLY, REALLY nice we need to also store
the previous filter options to be sure the element we try to keep on top
was valid for both old and new filters. I would rather do this later though
since this smell a lot like feature creeping ;)
Remove no longer needed display options:
* Current Scene (replaced by View Layer/Collections)
* Visible (replaced by filter)
* Selected (same)
* Active (same)
* Same Type (same-ish)
How about All Scenes? I have a patch that will come next to replace the current
behaviour and focus only on compositing. So basically stop showing the objects
and show only view layers, their passes and collections, besides freestyle.
Also, while at this I'm also reorganizing the menu to keep View Layer and
Collections on top.
Developer notes:
* Unlike the per-object filtering, for collections we need to filter at tree
creation time, to prevent duplication of objects in the outliner.
Acknowledgements:
Thanks Pablo Vazquez for helping testing, thinking some design questions
together and pushing this to its final polished state as you see here.
Thanks Sergey Sharybin and Julian Eisel for code review. Julian couldn't do a
final review pass after I addressed his concerns. So blame is on me for any
issue I may be introducing here. Sergey was the author of the "preserve
scrolling position" idea. I'm happy with how it is working, thank you.

This moves window overlay from hard coded flags into drawing callbacks.
It also supports snapping (holding Ctrl).
|
|
The original name came from a cheap conversion of the "active layer" option
to "active render layer" and then "active view layer".

Solves these security issues from T52924:
CVE-2017-12102
CVE-2017-12103
CVE-2017-12104
While the specific overflow issue may be fixed, loading the repro .blend
files may still crash because they are incomplete and corrupt. The way
they crash may be impossible to exploit, but this is difficult to prove.

Those are not used anymore.

Those are not used by new dependency graph and are not needed for properly
created rigs with new granular nodes.

Before we were re-using newid pointer inside of ID structure where we were
storing pointer to an original datablock.
It seems there is no way we can avoid requirement of having pointer to an
original datablock, so let's stop obusing system which was only designed to
be a runtime only thingie. Will be more safe this way, without need to worry
about using any API which modifies newid.

Brushes themselves are still affected by the mask, but the viewport is not
showing the mask. This way it's easier to see details while sculpting.
