- * Shadowcasting during spiraling is initially lazy, flagging only the shadows'

- * end are all cells flagged HIDE_LATER flagged as HIDDEN. This is to handle
- * cases where obstacles to view sit right at the border of pre-estabilshed
- * shadows, therefore might be ignored if HIDDEN and not cast shadows on their
- * own that may slightly extend beyond the pre-established shadows they border.
