 Note that the REM generation is very demanding, in particular:
 
  * the run-time memory consumption is approximately 5KB per pixel. For example,
-   a REM with a resolution of 500x500 needs about 1.25 GB of memory, and
-   a resolution of 1000x1000 needs about 5 GB (too much for a
-   regular PC at the time of this writing).

    slow down the execution of the rest of the simulation. If you want
