Subject: I allways noticed that in the SDL mode, the gradient was sometimes different than... 
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=5fb74739c5f4eebd93fd85a16fd4e17d6ac2776b;p=supertux.git

I allways noticed that in the SDL mode, the gradient was sometimes different than the OpenGL. But when I did the function, everything was okay and in most of the gradients it worked fine.
Finally, gone to the code and corrected that. It was just a typo (screen->w was being used in green and blue calculation, instead of screen->h).
