The general idea of this change is to have a runtime data pointer
in the ModifierData, so it can be preserved through copy-on-write
updates by the dependency graph.
This is where subdivision surface modifier can store its topology
cache, so it is not getting trashed on every copy-on-write which
is happening when moving a vertex.
Similar mechanism should be used by multiresolution, dynamic paint
and some other modifiers which cache evaluated data.
This fixes T61746.
Thing to keep in mind, that there are more reports about slow
subdivision surface in the tracker, but that boils down to the
fact that those have a lot of extraordinary vertices, and hence
a lot slower to evaluated topology.
Other thing is, this speeds up oeprations which doesn't change
topology (i.e. moving vertices).

T62570 and T61796 show that we need two slightly different behaviors in
post-linking collection process:
* For linking, we never want to instantiate indirectly-linked
collections or objects.
* For appending however, since all collections and objects will become
local and hence need instantiation, we want to 'link to scene' all
collections first, better than instantiating the objects in the master
collection opf current scene.
The billboard particles were only used by Blender Internal. So until it is
supported by Cycles of Eevee there is no reason to keep it in the code and
UI.

The shaders are: `GPU_SHADER_3D_FLAT_SELECT_ID` and `GPU_SHADER_3D_UNIFORM_SELECT_ID`.
This commit allows the drawing of the mesh select ids to be done on a 32UI format texture.
This simplifies the shader that previously acted on the backbuffer and had to do an uint to rgba conversion.

Enable depth picking by default.
This adds new 'gpu_flag' since it's not so relevant to add GPU drawing
options into uiflag & uiflag2.
This resets the recently added smooth edge flag.
Recent changes to blendfile reading adding deferred reading of actual
data broke it, we cannot use the nifty `bhead + 1` to access data
anymore, since there is no guaranty that that block hass been fully
read.
Note that there is still one case in `read_file_thumbnail()`, however
loading of blendfile preview itself seems to be working fine... Maybe
@campbellbarton can double check that point (or knows of hands whether
it is OK there)?
Some uninitialized colormanagement data was breaking RNA acces for them,
exposed in batch preview management when generating previews for scenes
because we have to backup/restore scene and all its settings
before/after rendering it...
Make sure we don't reallocate arrays in the pointcache when not needed, the
size of a memory allocation can be slightly bigger than the requested size.
Also, use consistent check for shared cached in copy and free functions.
During screen to workspace/workspace-layout conversion, the first layout
of each workspace would be activated. For temporary full-screens, this
used to be the full-screen layout (IIRC), apparently it's now the
the layout to return to on "Back to Previous". So the 'previous' layout
would be activated, not the full-screen one.
When actually pressing "Back to Previous" now, the operator would first
free the active layout (which it assumes to be the temp full-screen -
wrongly in this case) and then try to activate the non-full-screen one,
causing use-after-free.
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).

Do not force to link indirectly linked collections into current scene,
that is usually not desired. Note that user can always add this link
manually if they want.
All this 'implicit instantiation' post-linking process is rather hairy
to get it correct, hope this time it's not breaking something else...
Requested by some users who prefer old wireframe precision.
Smooth wires are still enabled by defaults as they don't have a noticeable
perf impact.
Application restart is needed for changes to take effects.
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.
Now always refresh when the material changes. Depsgraph tag moved out
of the refresh function since that gets called on depsgraph update,
which should not trigger a second depsgraph update.
As discussed with @billreynish this makes little sense now that we don't
have a dedicated textured mode. We don't have a superior texture or shaded
mode anymore and we also cannot mix different engines together (workbench
with eevee/lookdev).
The only feature it removes is the possibility to hide textures for certain
object in solid mode.
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.
