In the ordered Abelian group of reals with the integers as a
distinguished subgroup, the projection of a finite intersection of
generalized halfspaces is a finite intersection of generalized
halfspaces. The result is uniform in the integer coefficients and
moduli of the initial generalized halfspaces.
