Fixed bug #1112 (retina display support) Vittorio Giovara 2011-02-01 02:21:50 PST with the attached patch, the opengles context will always use the maximum screensize available; this is particularly useful for supporting retina display on latest iphone. please note: Apple documentation warns that using the "upscaled" gl context actually uses more memory and bandwitdh, so it might be worth to let the user decide whether to disable it or not, either with a flag or a sdl function...
