+The `name` is the case-sensitive name of the PNG file (without the file name suffix) of the graphics file, and `number` is the rough number of instances of this spray that may be added to the map. The number is the average number of sprays that are normally placed on a random medium-sized island. For larger and smaller landscapes, this number will be automatically scaled up or down. Please note that this number only specifies a rough goal, the actual number of created sprays may vary and you may have to play a bit with this number in order to find a good value.
