Changed data initialization to fix warning

Twist Brush: Scale brush tip space per vertex

Twist Brush: Deform rotation space

Twist Brush: Rotate in brush tip space

Merge branch 'master' into sculpt-dev

Merge branch 'master' into soc-2021-vse-strip-thumbnails

Thumbnail Cache fix : thumbs get loaded and not cleared when preview on

Docs: improve poly_to_tri_count doc-string

It wasn't obvious this can be used for calculating the triangle index
from the polygon and loop index.

Cleanup: use eSpace_Type enum type

Cleanup: remove contents of endif() in cmake

This convention is no longer used for Blender's CMake files.

Merge branch 'master' into cycles-x

Cleanup: make BKE_mesh_loops_to_tessdata a static function

Docs: add additional notes on tessellation, update comments

Sculpt dyntopo: Don't calculate curvature info in topology rake if curvature
mode is not enabled.

Mesh: optimize object mode face tessellation

- Multi-thread BKE_mesh_recalc_looptri.

- Add BKE_mesh_recalc_looptri_with_normals,
this skips having to calculate normals for ngons.

Exact performance depends on number of faces, size of ngons and
available CPU cores.

For high poly meshes the isolated improvement to BKE_mesh_recalc_looptri
in my tests was between 6.7x .. 25.0x, with the largest gains seen in
meshes containing ngons with many sides.

The overall speedup for high poly meshes containing quads and triangles
is only ~20% although ngon heavy meshes can be much faster.

Mesh: minor optimization to concave quad check for tessellation

Use the face normal (when available) for a faster concave quad test.

Cleanup: clang-format

EEVEE: Cleanup: Replace lighting evaluation macro by functions

The functions need to be declared before main as prototypes.
The appended libs will use the resources (textures, UBOs) defined at
global scope.

This removes a bit of code duplication and some long macros.

Generate unique names for output attributes.
