What I am thinking of actually isn't that far off IMO, maybe we're
simply misunderstanding each other? :)
a) pull all libass specifics/dependencies out of the EOSD, vo and vf_ass
code and extract an indedependently usable interface while not breaking
any current functionality.
b) extend EOSD with RGBA bitmap support and possibly more; what exactly
depends on the possible use cases we can think of and what hardware is
capable of.
d) Modify spudec (and old-style OSD) to use the EOSD interface. IMHO
spudec is a good fit to be a generic higher-level subpicture interface
that deals with timing, caching, bitmap conversion, scaling, etc.

If we get as far as having a versatile low-level OSD rendering
interface, I doubt it'll happen.
