Maniphest Tasks: T70554

Differential Revision: https://developer.blender.org/D6014

Fix Delaunay 2d valid bmesh mode bug.

Wasn't checking for repeated vertices.
Also, made choices of edges to keep more aesthetically pleasing.

Build: prepare "make update" to work for new release cycle branching

Checking out release branches in submodules, and printing some more
informative messages when that fails.

Fix T61432: Sampling Subframes not working 2.8

Uncommented subframe logic and added correct time getter function (with subframe part in frame) to subframe update function

Fix T70640 EEVEE: Alpha hashed material is darker when alpha is not 1.0

Predivide all radiance components as the alpha effect comes from the hashed
transparency (pixel rejection).

GPU: show one-time startup warnings for old Intel drivers with known issues

This is pretty conservative. We do not show warnings for e.g. HD 4000 with the
latest drivers as they appear to be working mostly fine even if unsupported,
and there is nothing the user can do to improve things.

Ref T70520

GPU: show more descriptive labels on unsupported GPU dialog

Thanks to Ray Molenkamp for the help with the Windows implementation.

Fixes T70521

CMake: Move software-gl to generic install procedure

Removes custom logic from buildbot's packing step.

This also removes icons/ folder, but CMake was already copying the
icons to the root of the install folder.

Deps: Fix wrong LLVM prefix used for Mesa

It made it Mesa to be compiled with swrast rather than with llvmpipe.

Deps: Add libraries needed for Software GL

Only compiled on Linux.

Cleanup: typo, style

Fix make deps libtool detection on macOS

Buildbot: Correction to previous commit

Off-by-one calculating parent folders.

Buildbot: Attempt to point precompiled libraries to a correct folder

The CMAKE_SOURCES variable is not yet initialized when the buildbot
configuration is read. This is similar to the include of full release
configuration happening earlier in the file.

Buildbot: Point to pre-compiled CentOS 7 libraries

Buildbot: Checkout precomiled CentOS libraries

Fix missing clear of ID types tags

Got lost in previous optimization commit.

PyAPI: drop Vector requirement for tessellate_polygon

Use mathutils_array_parse which converts any sequence of numbers.

PyAPI: avoid normal calculation for tessellate_polygon

Use fixed normal for 2D input, no need to calculate it.

Fix T70594: mathutils.geometry.tessellate_polygon flips triangles

Some scripts will need to be updated to support this.
