File headers: SPDX License migration Use a shorter/simpler license convention, stops the header taking so much space. Follow the SPDX license specification: https://spdx.org/licenses - C/C++/objc/objc++ - Python - Shell Scripts - CMake, GNUmakefile While most of the source tree has been included - `./extern/` was left out. - `./intern/cycles` & `./intern/atomic` are also excluded because they use different header conventions. doc/license/SPDX-license-identifiers.txt has been added to list SPDX all used identifiers.

Baking: new method to generate margin, based on adjacent faces This significantly reduces discontinuities on UV seams, by giving a better match of the texture filtered colors on both sides of the seam. It works by using pixels from adjacent faces across the UV seam. This new option is called "Adjacent Faces" and is the default. The old option is called "Extend", and extends border pixels outwards.

Bake: add UDIM tile baking support Works for both Cycles and multires bake. Triangles are baked to multiple UDIM images if they span across them, though such UV layouts are generally discouraged as there is no filtering across UDIM tiles. The bake margin currently only works within UDIM tiles. For the extend method this is logical, for the adjacent faces method it may be useful to support copying pixels from other UDIM tiles, though this seems somewhat complicated. Fixes T95190 Ref T72390
