These casts cast const away temporarily; they are safe, because the pointers that are initialized point to const data. But this is nevertheless not nice and leads to warnings when using -Wcast-qual. blend_modes.c generates 546 (2*39*7) such warnings which is the majority of such warnings for FFmpeg as a whole. vf_blend.c and vf_blend_init.h also use this pattern; they have also been changed.
