Subject: Use SCREEN_WIDTH/HEIGHT instead of SDL_RendererGetViewport(), as logical coordinates... 
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=d3414c1920bb735fc6cec95238aa71053ca5cbe4;p=supertux.git

Use SCREEN_WIDTH/HEIGHT instead of SDL_RendererGetViewport(), as logical coordinates might be different then physical
