New to the patch series after reordering things for landing smaller chunks.
This will essentially enable modifiers from clients that were just enabled in previous patches. A client could use the modifiers by setting all of them at create, but had no way to actually query them after creating the surface (ie. stupid clients could be broken before this patch, but in more ways than this). Obviously, there are no modifiers being actually stored yet - so this patch shouldn't do anything other than allow the API to get back 0 (or the LINEAR modifier).
