        Description

        G1 memory management uses a translation factor that corresponds, for auxiliary data structures, how many bytes of the heap map to a single byte of the given auxiliary data structure.

        This is used during initialization of the memory mappers.

        At the moment we hardcode these values, gathering it from various places, but it would be nicer if the data structure itself provided a getter for this.
