### Thread safety
In general, it is **safe** to create a filter chain instance from a different thread, but drawing filter passes **must be
externally synchronized**. The exceptions to filter chain creation are in OpenGL, where creating the filter chain instance
is safe **if and only if** the thread local OpenGL context is initialized to the same context as the drawing thread, and
in Direct3D 11, where filter chain creation is thread-unsafe if the `ID3D11Device` was created with
`D3D11_CREATE_DEVICE_SINGLETHREADED`.
In general, it is **safe** to create a filter chain instance from a different thread, but drawing frames requires
**externally synchronization** of the filter chain object. Additionally, filter chain creation requires external synchronization
of the graphics devices queue where applicable, as loading LUT textures requires submission of commands to the graphics queue,
unless the `filter_chain_create_deferred` methods are used.
OpenGL has an additional restriction where creating the filter chain instance in a different thread is safe **if and only if**
the thread local OpenGL context is initialized to the same context as the drawing thread.
