Hey,
I'm working on a project using gage2d. When I add more than 2 layers using a parallax, no error is thrown but the display stops updating.

parallax = new Parallax();
parallax.addMap(map1);
parallax.addMap(map3);
parallax.render(g);

The above code adds a blank layer on the bottom, and a layer filled with "tile1.png" on top.
It works perfectly with 2 layers, but if you remove the comment on the line that says parallax.addMap(map2), nothing is displayed.
