* Often times now the only reason OpenJpeg doesn't work is because it requires Glibc 2.4 The error messages reflect that. * In J2kDecoder module, It stops trying to decode modules if it encounters a dllnotfound exception and instead sends a full resolution layer that causes the texture sender to only send the full resolution image. (big decrease in texture download speed, but it's better then nasty repeating error messages)
