Using ClangBuildAnalyzer on the whole Blender build, it was pointing out that BLI_math.h is the heaviest "header hub" (i.e. non tiny file that is included a lot). However, there's very little (actually zero) source files in Blender that need "all the math" (base, colors, vectors, matrices, quaternions, intersection, interpolation, statistics, solvers and time). A common use case is source files needing just vectors, or just vectors & matrices, or just colors etc. Actually, 181 files were including the whole math thing without needing it at all. This change removes BLI_math.h completely, and instead in all the places that need it, includes BLI_math_vector.h or BLI_math_color.h and so on. Change from that: - BLI_math_color.h was included 1399 times -> now 408 (took 114.0sec to parse -> now 36.3sec) - BLI_simd.h 1403 -> 418 (109.7sec -> 34.9sec). Full rebuild of Blender (Apple M1, Xcode, RelWithDebInfo) is not affected much (342sec -> 334sec). Most of benefit would be when someone's changing BLI_simd.h or BLI_math_color.h or similar files, that now there's 3x fewer files result in a recompile. Pull Request #110944
