yes, i think it's not difficult, should i make a new spu/vob drawing 
function like spudec/vobsub_draw(mp_osd_obj_t *obj, int dxs, int dys) just 
like other sub/osd drawing function
>partial updates (so half sub on image half under image could work well)
there is no problem with half sub, it works perfectly on my machine(must 
with the cut sub patch)
