This patch allows the Voronoi node to operate in 1D, 2D, and 4D space.
It also adds a Randomness input to control the randomness of the texture.
Additionally, it adds three new modes of operation:
- Smooth F1: A smooth version of F1 Voronoi with no discontinuities.
- Distance To Edge: Returns the distance to the edges of the cells.
- N-Sphere Radius: Returns the radius of the n-sphere inscribed in
the cells. In other words, it is half the distance between the
closest feature point and the feature point closest to it.
And it removes the following three modes of operation:
- F3.
- F4.
- Cracks.
The Distance metric is now called Euclidean, and it computes the actual
euclidean distance as opposed to the old method of computing the squared
euclidean distance.
This breaks backward compatibility in many ways, including the base case.

This patch rewrites the Mapping node to support dynamic inputs. The
Max and Min options have been removed. They can be added as Min and
Max Vector Math nodes manually.
Texture nodes still use the old matrix-based mapping. A new SVM node
`NODE_TEXTURE_MAPPING` has been added to preserve this functionality.
Similarly, in GLSL, a `mapping_mat4` function has been added.

This patch extends perlin noise to operate in 1D, 2D, 3D, and 4D
space. The noise code has also been refactored to be more readable.
The Color output and distortion patterns changed, so this patch
breaks backward compatibility. This is due to the fact that we
now use random offsets as noise seeds, as opposed to swizzling
and constants offsets.

Since OpenImageDenoise requires a CPU with SSE 4.1 or newer,
let the node act as passthrough on unsupported CPUs and display
a message in the node itself.
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.

Add Multiply, Divide, Project, Reflect, Distance, Length, Scale, Snap,
Floor, Ceil, Modulo, Fraction, Absolute, Minimum, and Maximum operators
to the Vector Math node. The Value output has been removed from operators
whose output is a vector, and the other way around. All of those removals
has been handled properly in versioning code.
The patch doesn't include tests for the new operators. Tests will be added
in a later patch.

The Normal vector socket in the Normal node wasn't drawn properly and
couldn't be controlled. Additionally, the socket name was drawn over it.
This happened because the socket had a default value of a zero vector.
To fix this, we set the default value to the unit vector `(0, 0, 1)`.
Moreover, we don't draw the UI name if the subtype is `PROP_DIRECTION`.

If the option is enabled, the output is clamped to the target range.
The target range is [To Min, To Max]. The option is enabled by default.
The clamp option is implemented in EEVEE by linking to the `clamp_value`
GLSL function. And it is implemented in Cycles using a graph expand
function.

Change the default drawing method of vector sockets to use a column layout.
This allows more interactive use of nodes and avoids the one or two clicks
needed to edit vector sockets in the old default component layout.
Developers may still use the component layout by flaging the socket with the
`SOCK_COMPACT` socket flag. For now, we choose to draw the SSS scale vector
of the Principled and SSS nodes in a compact form because they don't require
much interactivity.

Don't allow changing it for painted images until they have been saved, similar
to sidebar panels. This could be solved better, for now the important thing is
not to lose changes.
Cycles now uses the color space on the image datablock, and uses OpenColorIO
to convert to scene linear as needed. Byte images do not take extra memory,
they are compressed in scene linear + sRGB transfer function which in common
cases is a no-op.
Eevee and workbench were changed to work similar. Float images are stored as
scene linear. Byte images are compressed as scene linear + sRGB and stored in
a GL_SRGB8_ALPHA8 texture. From the GLSL shader side this means they are read
as scene linear, simplifying the code and taking advantage of hardware support.
Further, OpenGL image textures are now all stored with premultiplied alpha.
Eevee texture sampling looks a little different now because interpolation
happens premultiplied and in scene linear space.
Overlays and grease pencil work in sRGB space so those now have an extra
conversion to sRGB after reading from image textures. This is not particularly
elegant but as long as engines use different conventions, one or the other
needs to do conversion.
This change breaks compatibility for cases where multiple image texture nodes
were using the same image with different color space node settings. However it
gives more predictable behavior for baking and texture painting if save, load
and image editing operations have a single color space to handle.

BF-admins agree to remove header information that isn't useful,

- 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 is in order to make the API more multithread friendly inside the
draw manager.
GPU_shader_get_uniform will only serve to query the shader interface and
not do any GL call, making it threadsafe.
For now it only print a warning if the uniform was not queried before.
Too many things done wrong in original rBd12b3767f81d to list them all
here, hopefully nothing bad sneaked in again this time :|
Also cleaned up a little the 'sort by name', even though (since we only
have two options by default, sort by index and by name) we can abuse it
as a binary option for now, this is not a bitflag...
Now, it was possible to invert the order of the UIlist using the filter, but it was impossible to know if the list was inverted or not.
The problem with this is that any other element depending of this value could not be adjusted.
See https://devtalk.blender.org/t/how-to-access-uilist-properties/2268
The new parameter allows to set the reverse order by default. When the list is set as reverse, it cannot be inverted again, so the invert button is removed of the filter.
This change is needed to fix a requested feature for Grease Pencil (T56985) and because a lot of 2D softwares use the drawing layers in the inverse order used in Blender.
In a real world it is very weird to disable AA on a mask,
it will give ugly looking result. For some fast preview
passes (like in the node preview) the system can decide
to disable AA without asking user to do anything.
One thing we can consider doing is to remove Feather
option as well. If real compo becomes measurably slower
in cases when mask has no real feather, we can disable
feather internally, without user input. Disabling
feather in the interface is like making things faster
but giving a wrong result, which doesn't sound that
helpful either.

Film-like curves for the RGB Curve node (Compositor) and Curve Modifier
(Sequencer)
Film-like curves originated from Adobe.
"It’s an RGB curve where the tone curve is applied on the largest and smallest value, and then the middle value is adapted to keep a constant hue as defined by RGB-HSL/HSV. In terms of look and saturation increase it’s very similar to a pure RGB curve, more so than a HSL-L curve or HSV-V curve, but some color shift problems are avoided."
Other tools like Natron, Krita and RawTherapee have implemented this curve tone.
