Well, as the title of the post says, everything is reversed, the compass, the cells and everything that has to do with images. I leave the link of the repository that will be the best to see what the problem is.
Let's see if someone who controls more and that I be with this every day can help me, bacause with previous libraries works, but at the moment of the update no.
JOGL 1 TextureIO was renamed AWTTextureIO in JOGL 2 and TextureIO in JOGL 2 became an equivalent of AWTTextureIO but with nothing about AWT. I suspect it might be a root cause of your problem, the images aren't completely reversed, there is only a vertical inversion.
