Line draw mode was boring, didn't find anything interesting

It is -C-D-C-D-C-D except write is free cycle when in onedot mode and no pixel needs to be drawn. (nothing new here)

3 free cycles between write to BLTSIZE and first blit cycle are also free (this isn't exactly emulated yet) but this can't fix above demo either..

ADDED: I guess copper and blitter cycles don't align properly causing lost cycles (demo writes blitter registers using copper)
