   Some ideas to help with tiling Image WorldObject for heatmaps:

   from math import ceil
   from itertools import product
   
   chunk_size = 128
   
   x_chunks = range(ceil(mcorr.shape[1] / chunk_size))
   y_chunks = range(ceil(mcorr.shape[2] / chunk_size))
   
   chunks = list(product(x_chunks, y_chunks))
   # chunks is the position of each chunk
   
   start_ixs = [list(map(lambda c: c * chunk_size, chunk)) for chunk in chunks]
   stop_ixs = [list(map(lambda c: c + chunk_size, chunk)) for chunk in start_ixs]
   
   grid = list()
   for start, stop in zip(start_ixs, stop_ixs):
       x0, y0 = start
       x1, y1 = stop
       grid.append(data[:, x0:x1, y0:y1].mean(0))

   So we've decided histogram is not happening because current libs more than good enough for histograms, as far as I've experienced.
