BLI: Add Cycles compatible Perlin noise

This patch adds new Perlin noise functions to BLI. The noises are compatible
with the shading texture noises in EEVEE, SVM, and OSL.

The existing Jenkins hash functions couldn't be used because they are not
compatible with the shading implementations and an attempt at adjusting the
implementation will break compatibility in various areas of Blender. So the
simplest approach is to reimplement the relevant hashing functions inside the
noise module itself.

Additionally, this patch also adds a minimal float4 structure to use in the
interface of the noise functions.

Fix T78803: Bad widget drawing with the R600g driver

The SB back-end optimizer for the mesa R600g driver corrupts the vertex
shader for widget drawing. This will not be fixed upstream because SB is
getting replaced as part of the new NIR path. This was thought to be an
issue with instancing and an attempted fix was submitted in D8374, but
it did not fix the issue.

This patch reimplements the array look-up part of the code using switch
case as a workaround and removes the old workaround implemented as part
of D8374.

Curves: add taper mode option

Currently, when a taper object is specified, the radius of the spline is
ignored. This patch adds a new option to control how the taper object
affect the effective radius of the spline. The option allow three modes
of operation:

- Override: The old method. The radius of the spline is ignored and
- Multiply: The radius of the spline is multiplied by the taper radius.
- Add: The radius of the spline is added to the taper radius.

Python: Add to_curve method to the object API

This patch adds a to_curve method to the Object ID. This method is
analogous to the to_mesh method. The method can operate on curve and
text objects. For text objects, the text is converted into a 3D Curve ID
and that curve is returned. For curve objects, if apply_modifiers is
true, the spline deform modifiers will be applied and a Curve ID with
the result will be returned, otherwise a copy of the curve will be

The goal of this addition is to allow the developer to access the splines
of text objects and to get the result of modifier applications which was
otherwise not possible.

Cleanup: Remove using-directive from freestyle headers

The header files in freestyle utilize the using-directive at the global
file scope. This is a bad practice as it pollutes the global name space
causing possible ambiguous reference compilation errors. In particular,
the DNA files that are included by freestyle will cause those ambiguous
reference errors when the developers adds a DNA member with a type name
that also exist in the Freestyle name space, such as Curve and possibly

This patch does the minimal work needed to resolve that by moving the
using-directives from the headers into the corresponding translation

Bmesh: Deprecate deform parameter of from_object()

The deform parameter of the Bmesh from_object method is deprecated,
always assumed to be True, and will be removed in version 3.0.

That is because the cases where it is False don't work correctly and are
subject to memory leaks. One of the symptoms of the incorrect behavior
is the application of constructive modifiers twice if the input object
is an evaluated one, as demonstrated in D10053.

Fix: Bmesh from_object applies modifiers twice

The Bmesh from_object method applies modifiers twice when the input
deform is enabled and the input depsgraph is a render one.

The evaluated object already have modifiers applied, and
mesh_create_eval_final() applies modifiers again. To fix this, the
BKE_mesh_new_from_object() function is used instead.

UI: Only draw node menu search if categories exist

Currently, the search operator in the node add menu NODE_MT_add is drawn
even if no node categories exists. This patch only draws the operator if
at least one node category passes the poll.

This patch is needed because some add-ons use custom search operator and
do not register node categories. In this case, it is undesirable to have
a search operator drawn that do nothing and is not used. One such add-on
is Animation Nodes.

Cycles: AVX implantation of Perlin noise.

This patch adds an AVX implementation of Perlin noise in Cycles.
An avxi type was also added as a utility based on the respective
type in Intel Embree.

Only 3D and 4D noise were implemented, there is no benefit for
utilizing AVX in 1D and 2D noise. The SSE trilinear interpolation
function was used in the AVX implementation because there is no
benefit from using AVX in interpolating the last three dimensions.
