Deleted a call to X__PumpEvents at the end of X11_GL_InitExtensions(). This function is being called from SDL_RecreateWindow at a point when the numwindows value in is incorrect. The result is that an illegal access is being made in X_PumpEvents when it tries to look up the windows ID of the source of an event. Taking out that call does not seem to have any effect on the testgl. But, I would be happy if someone else took a look at this problem and found a fix higher up the stack.
