For an input grid, flag cells near the previously flagged cells for creating buffer zone.
Shift by + or - 1 in either direction to do bitwise calculus for proper nesting, buffering, etc. similar to cshift on CM machine. includes periodic buffering as well.
NEWER VERSION: DOES ALL DIRS AT SAME TIME rectflags array has been augmented by enough border cells to do buffering in place in the grid later will look to see if flagged pts are properly nested
- Parameters
-
rectflags array to be flagged ilo global i index of the left border of the grid being projected to (being flagged) ihi global i index of the right border of the grid being projected to (being flagged) jlo global j index of the lower border of the grid being projected to (being flagged) jhi global i index of the upper border of the grid being projected to (being flagged) mbuff width of the buffer zone
