Summary [GFC] Resolve negative grid lines against the explicit grid track count

In order to make sure that line numbers are relative to the implicit grid we need to slightly transform any negative line numbers. By offsetting them by the number of explicit tracks we can make them relative to the explicit grid (e.g. -1 maps to the first line in the implicit grid). Then when we know how many implicit lines there are before the grid we can make all of the line numbers relative to the entire (implicit) grid
