Image with non-square pixels

Display image object with non-square pixels (disks, hexagons, octagons, rhombus)

imageWithNonSqrPix mimics the high-level form of the builtin function "image" but it displays image object with non-square pixels (disks, hexagons, octagons, rhombus).
You can specify the shape of the pixels and the pattern used to align them.
Run the demos for a better understanding of the concept.
I developed this code mostly for fun. Could it be useful for someone ? Let me know.
