generator with a local one. It's not thread safe and will not give repeatable results, so in most cases it should not be used. Also fixes #34992 where the noise texture of a displacement modifier was not properly random in opengl animation render, because the seed got reset to a fixed value by an unrelated function while for final render it changed each frame.
