 Minor change to rcollate to allow explicit byte records to
 be any specified length without checks against header input.

+row counts to Tregenza, but starting from a different
+azimuth and reversing row directions at adjacent altitudes.
+
+Added optimization for long argument lists and arrays in
+the calcomp routines used for rendering and in rcalc, etc.
+
+Added error estimate spreading to ambient super-sampling
+algorithm (-as) to improve performance especially in
+scenes with sharp cut-offs.
