Function JobBuild.Partition

int Partition<TAxis> (

NativeArray<int>	indices
int	startIndex
int	endIndex
NativeArray<float3>	positions
float	splitPoint

)

Moves every agent above splitPoint on the given axis to the end of [startIndex, endIndex).

Returns the index where the upper partition begins.

Takes the positions as a plain array rather than a strided NativeSlice: a slice indexes through a stride held in a struct field, which costs a multiply per access and blocks the coordinate read from folding into a constant offset.
