Sculpt Symmetrize: Initial commit

Fix C-linkage warning on Clang

After macro expansion, there would be C++ code in code with C linkage
(`extern "C"`). Clang warned about this.
Make sure the expanded C++ code always uses C++ linkage. Will commit this to
master soon.

USD Import: braces for if/else statments.

USD Import: declare local functions static.

This fixes compiler warnings.

USD Import: USDVolumeReader code cleanup.

Removed unused variable and unnecessary function call.
Replaced C-style cast with static_cast.

Geometry Nodes Curves: Cleanup

USD Import: simplify conditional logic.

Simplified conditional statement with early return.

USD Import: declare local functions static.

This fixes compiler warnings.

Cleanup: Fix typo in NURBSpline class name

Geometry nodes curves: Transform curve from object info node

Object: Make flash animation slower

Object: Use theme select color for animation

Geometry Nodes Curves: Support curves in the join geometry node

Merge branch 'master' into sculpt-dev

USD Import: Fix USDGeomReader casts.

Changed reinterpret_cast() to dynamic_cast() when
casting from USDPrimReader to USDGeomReader in mesh
sequence cache modifier callbacks.

Geometry Nodes Curves: Add initial support for poly splines

USD Import: USDGeomReader API cleanup.

Removed empty USDGeomReader create_object() and read_object_data()
functions. Made USDGeomReader::read_mesh() abstract virtual. Made
USDGeomReader::topology_changed() virtual. Marked
SDMeshReader::read_mesh() as override, to silence warnings.

Geometry nodes curves: Support instancing on control points

Geometry Nodes Curves: Implement copying a curve

This makes the spreadsheet pinning work as well.
