- Was setting active state, making it necessary to backup/restore
active object in cases where this isn't needed.
Existing scripts are explicitly setting the active object when needed.
- Use a boolean select arg (toggle selection wasn't used anywhere).
- Add an optional view layer argument since scripts should be able to
operate outside the user context.
We already had a BKE_main.h header, no reason not to put there
Main-specific functions, BKE_library has already more than enough to
handle with IDs and library management!
Simple find_nearest relies on a heuristic for efficient culling of
the BVH tree, which involves a fast callback that always updates the
result, and the caller reusing the result of the previous find_nearest
to prime the process for the next vertex.
If the callback is slow and/or applies significant restrictions on
what kind of nodes can qualify for the result, the heuristic can't
work. Thus for such tasks it is necessary to order and prune nodes
before the callback at BVH tree level using a priority queue.
Since, according to code history, for simple find_nearest the
heuristic approach is faster, this mode has to be an option.
This reverts reverting commit rB55324b8a2e6799300, and do proper 'cleanup' (sigh)
in gtest as well.
Sorry for the noise, did not understood what had happened here
immediately. :/
If the user only needs insertion and removal from top, there is
no need to allocate and manage separate HeapNode objects: the
data can be stored directly in the main tree array.
This measured a 24% FPS increase on a ~50% heap-heavy workload.

Currently some modes share tool keymaps, we might want to disable
this since it's confusing editing one thing in multiple places.
However this should be resolved in the tool definitions.
Terms get/set don't make much sense when casting values.
Name macros so the conversion is obvious,
use common prefix for easier completion.
- GET_INT_FROM_POINTER -> POINTER_AS_INT
- SET_INT_IN_POINTER -> POINTER_FROM_INT
- GET_UINT_FROM_POINTER -> POINTER_AS_UINT
- SET_UINT_IN_POINTER -> POINTER_FROM_UINT
Simple isn't a good prefix for library names since
lots of unrelated modules could be called 'simple'.
Include 'py' in module name since this is a subset of Python,
one of the main motivations for this is to be Python like/compatible.
Recently @sergey found that hard-coding evaluation of certain very
common driver expressions without calling the Python interpreter
produces a 30-40% performance improvement. Since hard-coding is
obviously not suitable for production, I implemented a proper
parser and interpreter for simple arithmetic expressions in C.
The evaluator supports +, -, *, /, (), ==, !=, <, <=, >, >=,
and, or, not, ternary if; driver variables, frame, pi, True, False,
and a subset of standard math functions that seem most useful.
Booleans are represented as numbers, since within the supported
operation set it seems to be impossible to distinguish True/False
from 1.0/0.0. Boolean operations properly implement lazy evaluation
with jumps, and comparisons support chaining like 'a < b < c...'.
Expressions are parsed into a very simple stack machine program
that can then be safely evaluated in multiple threads.

The ClayEngine was introduced to test the blender2.8 architecture during
development. As currently we have the wanted features implemented with
matcaps we are going to remove the clay engine as it was never intended
to be an official releasable engine
Note: The test cases are never run. But when enabled will be skipped as
they were implemented over the Clay Engine
This commit adds number formatting (thousands separator) to the baking panel. It also adds a new function to format memory sizes (KB/GB/etc) and applies it to the baking panel and scene stats. The new function is unit tested.

This adds Eevee render tests using the Cycles files. Currently it must
be enabled by setting WITH_OPENGL_RENDER_TESTS=ON. Once we have reference
images we can enable it by default.
Some of the Cycles and Eevee tests are also currently broken due to
modifier and particle changes.

OVERVIEW
* In 2.7 terminology, all layers and groups are now collection datablocks.
* These collections are nestable, linkable, instanceable, overrideable, ..
which opens up new ways to set up scenes and link + override data.
* Viewport/render visibility and selectability are now a part of the collection
and shared across all view layers and linkable.
* View layers define which subset of the scene collection hierarchy is excluded
for each. For many workflows one view layer can be used, these are more of an
advanced feature now.
OUTLINER
* The outliner now has a "View Layer" display mode instead of "Collections",
which can display the collections and/or objects in the view layer.
* In this display mode, collections can be excluded with the right click menu.
These will then be greyed out and their objects will be excluded.
* To view collections not linked to any scene, the "Blender File" display mode
can be used, with the new filtering option to just see Colleciton datablocks.
* The outliner right click menus for collections and objects were reorganized.
* Drag and drop still needs to be improved. Like before, dragging the icon or
text gives different results, we'll unify this later.
LINKING AND OVERRIDES
* Collections can now be linked into the scene without creating an instance,
with the link/append operator or from the collections view in the outliner.
* Collections can get static overrides with the right click menu in the outliner,
but this is rather unreliable and not clearly communicated at the moment.
* We still need to improve the make override operator to turn collection instances
into collections with overrides directly in the scene.
PERFORMANCE
* We tried to make performance not worse than before and improve it in some
cases. The main thing that's still a bit slower is multiple scenes, we have to
change the layer syncing to only updated affected scenes.
* Collections keep a list of their parent collections for faster incremental
updates in syncing and caching.
* View layer bases are now in a object -> base hash to avoid quadratic time
lookups internally and in API functions like visible_get().
VERSIONING
* Compatibility with 2.7 files should be improved due to the new visibility
controls. Of course users may not want to set up their scenes differently
now to avoid having separate layers and groups.
* Compatibility with 2.8 is mostly there, and was tested on Eevee demo and Hero
files. There's a few things which are know to be not quite compatible, like
nested layer collections inside groups.
* The versioning code for 2.8 files is quite complicated, and isolated behind
#ifdef so it can be removed at the end of the release cycle.
KNOWN ISSUES
* The G-key group operators in the 3D viewport were left mostly as is, they
need to be modified still to fit better.
* Same for the groups panel in the object properties. This needs to be updated
still, or perhaps replaced by something better.
* Collections must all have a unique name. Less restrictive namespacing is to
be done later, we'll have to see how important this is as all objects within
the collections must also have a unique name anyway.
* Full scene copy and delete scene are exactly doing the right thing yet.

This commit does two things:
- Adds an option to do the calculation in different color spaces (BT601
or BT709).
- Changes the default caluclation from legacy BT601 to BT709.
This affects several areas:
- UI areas (mainly scopes)
- ViewLevelsNode
- Several other nodes that use `COM_ConvertOperation.h`
