Pseudo motion blur using the extended palette + dithering with fillp.

The crux of making this happen is:

local defaultFills = {
  0b0000000000000000,   -- solid
  0b0000000000000001.1, -- single pixel missing
  0b0000010100000101.1, -- 4 pixels missing
  0b0101101001011010.1, -- half pixels missing
  0b1111101011111010.1, -- 4 pixels rendered
  0b1111111111111110.1, -- 1 pixel rendered
}

function resizeAndFill(input, outputLength)
  assert(outputLength >= 2, "behaviour not defined for n<2")
  local step = (#input-1)/(outputLength-1)
  local result = {}
  for x=1,outputLength do
    result
