-<rillian> so to use a global_ctx, you run your global data through a normal ctx
-<rillian> then call jbig2_make_global_ctx with the normal context
-<rillian> that does the (currently null) conversion
-<maskros> make_global_ctx after i fed it all the global stream data?
-<rillian> maskros: yes
-<rillian> and you pass the new global ctx object to jbig2_ctx_new() when you
-+create the per-page ctx
