If you're somewhat fluent in C/C++, it's not very difficult.

Try the following:

In line 2225 of lib/devices/swf.c, change the code

    msg("<trace> Placing image, shape ID %d, bitmap ID %d", myshapeid, bitid);
    i->tag = swf_InsertTag(i->tag,ST_PLACEOBJECT2);
    CXFORM cxform2 = gfxcxform_to_cxform(cxform);
    
swf_ObjectPlace(i->tag,myshapeid,getNewDepth(dev),&i->page_matrix,&cxform2,NULL);
to
    msg("<trace> Placing image, shape ID %d, bitmap ID %d", myshapeid, bitid); 
    int mcid = getNewID(dev);
    i->tag = swf_InsertTag(i->tag, ST_DEFINESPRITE);
    swf_SetU16(i->tag, mcid);
    i->tag = swf_InsertTag(i->tag,ST_PLACEOBJECT2);
    CXFORM cxform2 = gfxcxform_to_cxform(cxform);
    swf_ObjectPlace(i->tag,myshapeid,1,&i->page_matrix,&cxform2,NULL);
    i->tag = swf_InsertTag(i->tag, ST_END);
    i->tag = swf_InsertTag(i->tag, ST_PLACEOBJECT2);
    swf_ObjectPlace(i->tag,mcid,getNewDepth(dev),0,0,0);
