Usecase:
Say you want to populate a chessboard with pawns. 1 pawn particle for each square. You want to have 2 separate particle systems for white and black pawns containing 32 particles in each.
Once the first particle system (white pawns) has positioned its pawns randomly (eg based on vertex) you want to other particle system to position at the "vacant" spaces.
In this case it would be very convenient to be able to invert the seed of the first system in the second system so they would be mirror opposites thus populating the entire board without duplicate or vacant spaces.
A negative value in the seed input would become the opposite seed of the positive value / or a checker next to the seed box.
