I'm not sure if I can get this working without help, but will continue to try

@Iyad Ahmed (iyadahmed2001) Can you explain what you mean by "access issues"? Does it compile? Also, how serious of a renewal of the patch is this? I notice you keep abandoning and reclaiming it.

Has @Campbell Barton (campbellbarton) abandoned the effort?

None of your work on Blender seems to be this low-level so I'm just wondering what's going on.

Yes it compiles, sorry a typo I meant memory access issues

And yes unfortunately it still needs a lot of work to be ready, and it might not be useful in the end
