...
Now to roll back onto composite. Fingers crossed!

Thomas Harte
246b474a25
Removes ONE_BIG_LOCK, having effectively neutered it anyway.
...
Starts work on more explicit API usage validation. Maybe the issue isn't a race condition?

Add fix for data_type_size_ for owners that don't change texture pointer upon new modals.

Adds note on the buffering scan target's minor adaptation of data_offset.

Having learnt a bit more: eliminates Metal attribute tags, switches to more natural expression of structs.
...
Also thereby eliminates the need for a forced alignas(4) on various structs.

Modifies BufferingScanTarget to allow has-a relationship.
...
I might switch fully to has-a. Further consideration required.

Thomas Harte
4c9418f59a
Guarantees alignof(4) on all GPU-bound structures.
...
Taken as given: Metal's requirement here is reasonable enough that it'll either be the same as other frameworks, or at least possibly help them down a fast path.

72a8fef989
Switches to much more straightforward Line/LineMetadata storage.
...
Spoiler: covering this whole segment behind producer_mutex_ seems to resolve all output issues, so clearly the existing logic isn't functioning correctly. Making it simpler seems like a pretty obvious way to get to the bottom of that.

This has become the general producer mutex, might as well name it as such.
