Changes the size of the patch grid.

If the given patch grid coordinates are different than the ones in use, all turtles and links die, and the existing patch grid is discarded and new patches created. Otherwise, existing turtles and links will live if the grid coordinates are unchanged.

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

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).
