Subject Re: TLF2 Background manager

Well, once you see "tlf_internal" (or mx_internal, for that matter), that
implies that there isn't official support.

I'm not the expert in this code, but in a quick grep of it, it looks like
you can assign a backgroundManager to the textFlow.  IIRC, there is logic
that chooses which Factory to use for textlines and maybe you want to figure
out how to control that so it doesn't use TextFlowTextLineFactory and one of
the other ones that might honor the textFlow's backgroundManager, or maybe
it is just a bug and the factory should be checking for and using the
textflow's backgroundManager.
