This update brings along gif background and foreground support! You can now provide an overlay.gif or a background.gif if you'd like to use an animated image! If you'd rather stick to static images, then you can now also use JPG format if you so wish. However, note that JPG don't support transparency.

Also, transparency is properly supported for the default color of your palettes, meaning if you own a skyblock server, the void will show up properly!

As a last note, I've updated the test server to 1.15.1 so anyone can go check it out if you're missing some inspiration on how to use Cartographer2. It is currently using Falcon's Rock as its main world, so be sure to check that out if you like it too.

Here's the new default overlay and background gifs for those of you who missed it:
