NAME
     gpr_$inq_constraints - returns the clipping window and plane mask.

FORMAT
     gpr_$inq_constraints (window, active, plane_mask, status)

DESCRIPTION
     This routine returns the clipping window and plane mask used for the
     current bitmap.

   Output Parameters
     window
          The clipping window, in gpr_$window_t format.  This data type is 8
          bytes long.

     active
          Boolean (logical) value which specifies whether the clip window is
          enabled.  If the value is false, the clip window is disabled; if the
          value is true, the clip window is enabled.

     plane_mask
          The plane mask, which specifies the active bitmap plane(s), in
          gpr_$mask_t format.  This is a 2-byte integer.

     status
          Completion status, in status_$t format.
