Based on the original patch by Vaishnav S (@padthai), this adds
support for temperature units. Initially supported units are Celsius,
Kelvin, and Fahrenheit.
The units aren't used anywhere with this commit. Those changes should
happen in separate patches by adding PROP_TEMPERATURE to RNA property
definitions. But it should be ensured that the various solvers and
simulations actually properly use real units.
The complexity of some of the changes comes from the fact that these
units have offsets from each other as well as coefficients. This also
makes the implementation in the current unit system troublesome.
For example, entering 0C evaluates correctly to 273K, but 0C + 0C
doubles that result, because each unit value is evaluated separately.
This is quite hard to solve in the general case with Blender's current
unit system, though, so it is not handled in this commit.

Local datablocks (including overrides) need to have a unique name, which
can then differ from the reference linked one (especially when there are
several local overrides of a same linked data).
Issue is, ID name is a 'rna name property', and as such used as
reference when dealing with override of collections of IDs, so we cannot
have a changing name.
The solution implemented here should work and is simple, but it may have
some issues in corner cases (time will say), it is not really robust.
Alternative solution would be to store ID pointers as reference in
override operations, instead of there name. But that would potentially
add quiet a lot of overhead to foreach looping in `lib_query.c`.

Only the volume object is exposed in the user interface. It is based on OpenVDB
internally. Drawing and rendering code will follow in another commit.

Hair and PointCloud object types are hidden behind a WITH_NEW_OBJECT_TYPES
build option. These are unfinished, and included only to make it easier to
cooperate on development in the future and avoid tricky merges.

Good to be explicit about the fact that we may still use the pixel
property sub-type when DPI will be applied.

Depsgraph RNA pointer would generate infinite loop in override comparisons.
Depsgraph pointer should never be considered here anyway, this is purely
runtime data.

Also correct some outdated symbol references,
add missing 'name' commands.

The old layout of `PointerRNA` was confusing for historic reasons:
```
typedef struct PointerRNA {
struct {
void *data;
} id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
This patch updates it to:
```
typedef struct PointerRNA {
struct ID *owner_id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
Throughout the code base `id.data` was replaced with `owner_id`.
Furthermore, many explicit pointer type casts were added which
were implicit before. Some type casts to `ID *` were removed.

To fully support storing colors as a custom property, it is necessary
to allow switching the property UI to the standard color picker button.
That means in effect supporting custom property subtype values.
Change RNA_property_subtype to look for a 'subtype' string field
in _RNA_UI and parse it as an enum value. To minimize performance
impact, only do it if the property is an array; also, don't use
the custom subtype during RNA path parsing.
On the python side, allow setting some most useful seeming values
from the custom property settings editor.
Also, since some color picker code seems to run into a risk of
buffer overruns if the array size is wrong, check the size in
the UI layout code to be safe.

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.

Mark specific properties as no-dependency-graph tag.
This is needed to avoid a centralized Copy-on-Write tag from RNA

While \file doesn't need an argument, it can't have another doxy

This affects point, spot and area lights. Sun light strength remains without
a unit. This change does not affect .blend file compatibility in any way, as
with the rest of the unit system it's purely a display and editing feature.
Not used for Cycles yet, that will be done after unifying the settings with
Eevee.

Move \ingroup onto same line to be more compact and

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.

The same icons are reused for "hide" and "show" properties, which need

We were using int's for bool arguments in BKE,
just to avoid having wrapper functions.
|
|
|
|
Material slots are a real pain to get working, due to all the black
magic they do to hide object vs. obdata storage of the material...
Currently hitting an order problem - we need to always set 'link' (to
object or obdata) property of the slot first, before we set its
material... *super-sigh*

We are already running out of available flags in main, generic int, and
everytime I work on static override I find new special cases that will
need new specific propflag, so...
|
|
Does not yet support applying those operations, only detecting
insertions and generating matching rules was already rather complicated.
Also got rid of ;ost rna_path string allocation in collection diffing
code, could help a bit with speed too.

This commit essentially introduces a new RNA property flag, which when
set prevents affected property from being processed at all in comparison
code (also used to automatically generate static override rules).
The idea is to use it on very low-level data in RNA, like e.g. mesh's
geometry or psys' particles collections.
For now only applied to psys' particle collections, on the main mesh of
Agent327 pigeon, it goes from 100ms to 0.5ms on a full
auto-override-generating comparison...
Also added some new RNA property helper funcs to check on comparable and
overridable status.

Allows for each workspace to have it's own add-ons on display.
Filtering for: Panels, Menus, Keymaps & Manipulators.
Automatically applies to add-ons at the moment.
Access from workspace, toggled off by default
once enabled, add-ons can be white-listed.

Tired of searching through code to find which is what, and how to use it
in the C callback, everytime I need anot-so-common option...

This flag means that the pointer does not 'own' the data it references.
This is the case of nearly all ID RNA pointers (NodeTrees will probably
again be some nasty exception here :( ), but also several other cases.
That kind of information is mandatory for complex processing over whole
data-blocks done in RNA, like some static override tasks (advanced
comparison...).
|
|
|
|
This is essentially a huge refactor/extension of our existing RNA
compare & copy code, since static override needs more advanced handling here.
Note that not all new features are implemented yet, advanced things like
collections insertion/deletion are still TODO (medium priority).
This completes the ground work for overrides, remaining commits will be
about UI and some basic/testing activation of overrides for a limited
set of data-blocks & properties.

PYRNA_STACK_ARRAY use it.

The RenderResult struct still has a listbase of RenderLayer, but that's ok
since this is strictly for rendering.
* Subversion bump (to 2.80.2)
* DNA low level doversion (renames) - only for .blend created since 2.80 started
Note: We can't use DNA_struct_elem_find or get file version in init_structDNA,
so we are manually iterating over the array of the SDNA elements instead.
Note 2: This doversion change with renames can be reverted in a few months. But
so far it's required for 2.8 files created between October 2016 and now.

Practically all access to enum data is read-only.
|
|
|
|
Only add subclasses of: Menu, Panel, Header, UIList, Operator
This helps avoid unnecessary naming collisions,
