The problem was that the object and collection pointers in Base and
LayerCollection would get lost of file read. Normally such ID pointers would
be resolved by pointing to an ID_ID placeholder which has the datablock name,
and then replacing it will the real datablock. However ID_ID is only written
for directly linked datablocks.
This adds the concept of an indirectly linked datablock with a weak reference
to it. For this we write an ID_ID_WEAK_REF code, which is a reference that
will only be resolved if the datablock was read for another reason.

This change allows the user to select a renderpass in the 3d viewport.
Added support for external renderers to extend the `View3DShading` struct.
This way Blender doesn't need to know the features an external render engine wants to support.
Note that the View3DShading is also available in the scene->display.shading; although this is
supported, it does not make sense for render engines to put something here as it is really
scene/workbench related.
Currently cycles assumes that it always needs to calculate the combined pass; it ignores the
`pass_flag` in KernelFilm. We could optimize this but that was not in scope of this change

Better to make internal code naming match official/UI naming to some
extent, this will reduce confusion in the future.
This is 'breaking' scripts and files that would use that feature, but
since it is not yet officially supported nor exposed in 2.80, as far
as that release is concerned, it is effectively
a 'no functional changes' commit.
Forward compatibility with that version is already long gone, and removing
it means we can avoid running some complicated code on every file read/write.
This is just not practical to do for the code as a whole, and having it as an
exception for one specific data structure is not that helpful. This has only
been in the way for me when refactoring code.
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.
We already have different storages for cddata of verts, edges etc.,
'simply' do the same for the mask flags we use all around Blender code
to request some data, or limit some operation to some layers, etc.
Reason we need this is that some cddata types (like Normals) are
actually shared between verts/polys/loops, and we don’t want to generate
clnors everytime we request vnors!
As a side note, this also does final fix to T59338, which was the
trigger for this patch (need to request computed loop normals for
another mesh than evaluated one).

Use 'size' instead of 'len' to represent the size of data in bytes,
'len' is used for the result of 'strlen' or the length of an array
in some parts of 'makesdna.c' & 'dna_genfile.c'.
Also clarify comments and some variable names, no functional changes.
Avoids mixing these in with regular variables in code-completion.
Use char for pad members except for 'void *', to make size clearer.
Removed/shrink a few redundant padding vars which were >= 8 bytes.
While Buffering output is useful for file writing and memfile
compression it's redundant when the output is already buffered.
It doesn't make a significant difference for ZLIB
however it makes a moderate improvement for LZ4, see T56162.
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.
This commit adds another optional check (when `--debug-io` is set) on
write .blend process, to check and ensure all shape keys have their
'from' pointer properly set to their respective user ID.
This is intended to be used as debuging tool mostly (to try to detect
when/why some of those pointers can become NULL).
For now, it also systematically perform same checks/fixes when loading a
.blend file, to fix all broken ones laying around. Later we might move
that usage to a do_version instead, but for now think it's safer to
always perfom it (and it's rather cheap process anyway).
Does not make sense to keep that with BLO_writefile.h, this can also be
used by read code, and some other parts of Blender (like ed_undo.c
currently)...
This commit adds support for new curve tool and adds more functionalities to the existing primitives, including new handles, editing, stroke thickness curve, noise, preview of the real stroke, etc.
Thanks to @charlie for his great contribution to this improvement.
