Except for the Metsl runtime, in general, it is **safe** to create a filter chain instance from a different thread, but drawing frames requires
**external synchronization** of the filter chain object.
Filter chains can be created from any thread, but requires external synchronization of the graphics device queue where applicable

the thread local OpenGL context is initialized to the same context as the drawing thread. Support for deferral of GPU resource initialization
is not available to OpenGL.
The Metal runtime is **not thread safe**. However you can still defer submission of GPU resource initialization through the
`filter_chain_create_deferred` function.
### Quad vertices and rotations
All runtimes except OpenGL render with an identity matrix MVP and a VBO for with range `[-1, 1]`. The final pass uses a
Quad VBO with range `[0, 1]` and the following projection matrix by default.
