Changes the size of the patch grid.

If any coordinate is fractional, it will be rounded to the nearest integer towards zero (4.5 becomes 4, 10.9 becomes 10, -2.9 becomes -2).

If the new patch grid coordinates are different than the ones in use, all turtles and links die, the existing patch grid is discarded, new patches created, and the tick counter is cleared. However, if the grid coordinates are the same, the world state will remain unchanged.

Retaining references to old patches or patch sets is inadvisable and may subsequently cause runtime errors or other unexpected behavior.
