Your link really helped me out, furqan, thanks.
Why couldn't you figure it out? A point where I stumbled was, that I didn't know you can exceed the [0,1] interval when calculating the texture coordinates. That makes it a lot easier to jump from one side of the texture to the other with OpenGL doing all the interpolation and without having to calculate the exact position where the texture actually ends.
