   @brief
      Records point samples from a renderer and naively reconstructs the 
   underlying image by storing samples into the bin/pixel which they fall 
   into, overwriting previous samples, and not using any reconstruction 
   filter. Writes results out to the given file in a custom format upon 
   completion of rendering.
