	~~Although this provides a fairly~~ accurate ~~area~~ this ~~can lead to unwanted results~~ for ~~very small~~ objects ~~that are~~ smaller ~~then~~ the grid cell area. ~~When~~ the ~~cells~~ center point ~~does not intersect the~~ small object it ~~will not~~ be rasterized and ~~thus be part of~~ the simulation.		While more accurate, this method may fail for objects smaller than the grid cell area. If the cell center point misses a small object, it won't be rasterized and remains as traversable space in the simulation.

	To compensate for this situation the default option is '''combined''' center + outline. ~~Where~~ most objects ~~are rasterized via the optimal area solution (center point)~~ and small ~~objects are rasterized with the outline~~ to ~~prevent falling of the grid~~.		To compensate for this situation the default option is '''combined''' center + outline. This method uses center-point rasterization for most objects and outline rasterization for small ones to ensure coverage.
