When validating a Map Definition, Maestro should collect the number of unique colors found in all referenced Layer Definitions. If the total is > 256 or a color FDO expression was detected (implying a variable number of different colors), report a warning that the Map Definition may not be suitable for rendering as PNG8 images.
