From 5fb74739c5f4eebd93fd85a16fd4e17d6ac2776b Mon Sep 17 00:00:00 2001 From: Ricardo Cruz Date: Sat, 15 May 2004 14:19:01 +0000 Subject: [PATCH] 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).
