// To quickly know if a tile is inside a zone of micro-life, we subdivide the world into a grid. Each grid cell
// may be overlapped by [0, n] polygons of a micro-life zone. We don't want to store a full list for each cell of
// the grid, because such lists are repeated several times (it would end up wasting too much space). What we just need to keep is
// a set of possible polygon lists that can overlap a grid cell. Afterward, we just need a grid of index into
// the list of possible polygon lists.
// To do that : - we first store complete lists in each grid cells : this is done by several calls to drawPolyInBuildGrid
// - we search for redundant lists and store the result as index in the final grid. This is done in packBuildGrid
