                                   GRID
     Grid, as the name suggests, creates a grid pattern (a series of
     intersecting line segments). The following values are needed:

     Grid Size      - defines the spacing, both horizontally and
                      vertically of the intersecting line segments 
                      that will make up the grid.

     Line Size      - defines the thickness of the intersecting line
                      segments.

     RGB Color     \  adjust the appearance of the lines. The same rules 
     RGB Reflect    > that apply for standard color, reflect, & filter
     RGB Filter    /  are used in setting these values. This lets you 
                      create transparent (filter) or mirrored (reflect)
                      grid patterns.
