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.

Merge newboolean branch into master. This is for design task T67744, Boolean Redesign. It adds a choice of solver to the Boolean modifier and the Intersect (Boolean) and Intersect (Knife) tools. The 'Fast' choice is the current Bmesh boolean. The new 'Exact' choice is a more advanced algorithm that supports overlapping geometry and uses more robust calculations, but is slower than the Fast choice. The default with this commit is set to 'Exact'. We can decide before the 2.91 release whether or not this is the right choice, but this choice now will get us more testing and feedback on the new code. 2020-08-28 10:56:44 -04:00

Cleanup: Simplify dependencies for GMP math header Previously, the base math headers included GMP headers in all cases. This was problematic because we don't want all modules that use the math headers to depend on GMP, and the unnecessary includes could theoretically have detrimental effects to compile times. Now `BLI_math_mpq.hh` depends on `BLI_math_base.hh`, so if a file needs to use exact arithmatic, it can just include the former.
