Photo background #388
Description
Great thanks for your work at tiddly map.
I want to have additional feature for adding a photo as a background to have it repeat itself infinitely many times in all directions, up, down, left and right. Also the background for the map color to be able to change it according to the tiddly wiki theme. For example, if my tiddly wiki background's color is black, then my tiddly map is also black. If there is a transparent option, this would be awsome.
Many thanks,
Best
