    /* GL_APPLE_ycbcr_422 claims that its '2YUV' format, which is supported via the UNSIGNED_SHORT_8_8_REV_APPLE type
     * is equivalent to 'UYVY' format on Windows, and the 'YUVS' via UNSIGNED_SHORT_8_8_APPLE equates to 'YUY2'. The
     * d3d9 test however shows that the opposite is true. Since the extension is from 2002, it predates the x86 based
     * Macs, so probably the endianness differs. This could be tested as soon as we have a Windows and MacOS on a big
     * endian machine
