Type of multithreading allowed for filters in this graph. A combination
of AVFILTER_THREAD_* flags.
May be set by the caller at any point, the setting will apply to all
filters initialized after that. The default is allowing everything.
When a filter in this graph is initialized, this field is combined using
bit AND with AVFilterContext.thread_type to get the final mask used for
determining allowed threading types. I.e. a threading type needs to be
set in both to be allowed.
