First, I don't know what TextureLoader or newdawn.slick. Opengl are, so there is only limited information I can give about this.
OpenGL Doesn't like textures that are not powers of two if I recall. Is your texture a power of 2 for both height and width?
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
