This improves both code finding, for example "color ramp" now has its own file.
And now each node has its own namespace so function names can be simplified
similar to rBfab39440e94
This commit also makes all file names use snake case instead of camel case.

Earlier code assumed that the active strip was on the active track. This
commit detects when this assumption doesn't hold, and adds a more thorough
search of the active strip.
As a followup to 338c1060d5, apply the same change to the node
drawing callback. This helps to simplify code when the complexity
of a callback isn't necessary right now.
Currently there are a few callbacks on `bNodeType` that do the same
thing for every node type except reroutes and frame nodes. Having a
callback for basic things complicates code and makes it harder to
understand, and reroutes and frames are special cases in larger way.
Arguably frame nodes shouldn't even be drawn like regular nodes,
given that it adds a case of O(N^2) looping through all nodes.
"Unrolling" the callbacks makes it easier to see what's happening,
and therefore easier to optimize.

`GeometrySet` contains at most one component of each type.
Previously, a map was used to make sure that each component
type only exists once. The overhead of a map (especially with
inline storage) is rather large though. Since all component types
are known at compile time and the number of types is low,
a simple `std::array` works as well.
Some benefits of using `std::array` here:
* Looking up the component of a specific type is a bit faster.
* The size of `GeometrySet` becomes much smaller from 192 to 40 bytes.
* Debugging a `GeometrySet` in many tools becomes simpler because
one can easily see which components exists and which don't
This helps to tell when a pointer is expected to be null, and avoid
overly verbose code when dereferencing. This commit also includes
a few other cleanups in this area:
- Use const in a few places
- Use `float2` instead of `float[2]`
- Remove some unnecessary includes and old code
The change can be continued further in the future.
`IMB_transform` is used in VSE. It had a required crop parameter
for cropping the source buffer. This is not always needed.
In the image engine we want to use the use the `IMB_transform`
with wrap repeat. Both options are mutual exclusive and due
to performance reasons the wrap repeat is only available when
performing a nearest interpolation.
The asset metadata custom property `["is_single_frame"]` was set
incorrectly. Since this is intended for forward compatibility, including
being covered by the asset metadata indexing, it's important to have it
set correctly from the first release of Blender that includes the asset
browser.

This node calculates the dual of the input mesh. This means that faces
get replaced with vertices and vertices with faces. In principle this
only makes sense when the mesh in manifold, but there is an option to
keep the (non-manifold) boundaries of the mesh intact.
Attributes are propagated:
- Point domain goes to face domain and vice versa
- Edge domain and Face corner domain gets mapped to itself
Because of the duality, when the mesh is manifold, the attributes get
mapped to themselves when applying the node twice.
Thanks to Leul Mulugeta (@Leul) for help with the
ascii diagrams in the code comments.
Note that this does not work well with some non-manifold geometry,
like an edge connected to more than 2 faces, or a vertex connected to
only two faces, while not being in the boundary. This is because there
is no good way to define the dual at some of those points. This type
of non-manifold vertices are just removed for this reason.

Replace compare floats node with a generalized compare node. The node
allows for the comparison of float, int, string, color, and vector.
The datatypes support the following operators:
Float, Int: <, >, <=, >=, ==, !=
String: ==, !=
Color: ==, !=, lighter, darker
(using rgb_to_grayscale value as the brightness value)
Vector Supports 5 comparison modes for: ==, !=, <, >, <=, >=
Average: The average of the components of the vectors are compared.
Dot Product: The dot product of the vectors are compared.
Direction: The angle between the vectors is compared to an angle
Element-wise: The individual components of the vectors are compared.
Length: The lengths of the vectors are compared.

Now that we can store any dynamic attribute on the instances component,
we don't need the special case for `id`, it can just be handled by the
generic attribute storage. Mostly this just allows removing a bunch
of redundant code.
I had to add a null check for `update_custom_data_pointers` because
the instances component doesn't have any pointers to inside of
custom data.

When enabling or disabling a Mesh Sequence Cache modifier of an Object
with a hair particle system, the hair would switch positions. This is
caused because original coordinates in Blender are expected to be
normalized, and toggling the modifier would cause the usage of different
orco layers: one that is normalized, and the other which isn't.
This bug exposes a few related issues:
- if the Alembic file did not have orco data,
`MOD_deform_mesh_eval_get`, used by the particle system modifier, would
add an orco layer without normalization
- `MOD_deform_mesh_eval_get` would also ignore the presence of an orco
layer (e.g. one that could have been read from Alembic)
- if the Alembic file did have orco data, the data would be read
unnormalized
To fix those various issues, original coordinates are normalized when
read from Alembic and unnormalized when written to Alembic; and a new
utility function `BKE_mesh_orco_ensure` is added to add a normalized
orco layer if none exists on the mesh already, this function derives
from the code used in the particle system.

this can be decided and done, but think this default behavior also makes

Add flag to `BKE_bpath_traverse_id()` and friends to skip weak
references (see below). This makes a distinction between "this blend
file depends on that file" and "this blend file references that file,
but doesn't directly use its data". This distinction is for the Asset
Bundle install operator, which refuses to copy the blend file when it's
not self-contained.
Weak references are those that are not directly used by the blend file,
but are still present to allow path rewriting. For example, when an
Asset is loaded its originating blend file is saved in
`ID::library_weak_reference`; this reference is purely for deduplication
purposes, and not for actually loading any data.
