! The "grids-per-unit" is the "real" routing grid the user wants.  "Units"
! tells the program whether grids-per-unit is in grids-per-cm or
! grids-per-inch.  At the setup screen the user is able to select any one
! of the grids-per-unit routing grids, and to set via shift on or off.
! When the job is loaded into the router the program will match the
! routing grid and via shift with a grids-per-unit and viashift pair.
! The program will then use the router-grids-per-inch and viashift to
! initialize the router.  Any scaling between the "real" routing grid and
! the internal router-grids-per-inch will be automatically performed by
! the program.  This would happen for all the metric grids below and for
! english 50 grids-per-unit with viashift and english 20 grids-per-unit
! with viashift.
