This tool performs a range filter on an input image (`input`). A range filter assigns to each cell in the output grid the range (maximum - minimum) of the values contained within a moving window centred on each grid cell.

Neighbourhood size, or filter size, is specified in the x and y dimensions using the `filterx` and `filtery` flags. These dimensions should be odd, positive integer values (e.g. 3, 5, 7, 9, etc.).
