IIRC the original idea was that a buffer could be in video memory (preserved
but slow as hell to read)

and conditional replenish based codecs just update some pixels but leave the
remainder unchanged, they also dont read from the buffer so they would
theoretically benefit from such buffers

but IMHO its an obscure feature which is pretty unimportant
