Bug#1118405: Sculpting not possible in blender because brushes are missing

[Kenno Vanommeslaeghe]

Apologies; on second look, the root of the problem appears to be an 
upstream repository management mistake. Specifically, the 'assets' 
directory is not marked as part of the blender-v4.3-release and 
the blender-v4.4-release branches both in the source repository at 
https://projects.blender.org/blender/blender and the "official mirror" at 
https://github.com/blender/blender . The error was only corrected 
in blender-v4.5-release , so cloning the 4.3 or 4.4 branch from either 
repository will result in a source tree that effectively can't do 
sculpting because of the missing brushes.
