So, all we have to do is figure out how to make the transition, which seems a lot less weighty than something that will affect the environment for a long time. We need to consider the cross-version compatibility issues for both the window system and the kernel. That means an old window system with new kernel or new window system with old kernel should work as well as it does today. Today, an HMD display is presented as a normal output and applications can discover it through the window system and present an image on it by placing their image at the right location on the screen. To keep that working, we can't hide HMD outputs from an older window system. =2D-=20 =2Dkeith --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEw4O3eCVWE9/bQJ2R2yIaaQAAABEFAlnw8t4ACgkQ2yIaaQAA ABEahg//Y47417xLGk6o7McHR4XU/NSyyVGUcgCRGYzy9OD4vXGzEcZtF31X+vYA 1HSvaFQcli8yI3mNt+ZVKqISZ2tMg22wWT1M7NIoCqDCb4qJD1LPqBV+s5Sl6qXD ofCvAd5nyxgZ0jsiiY0xE2nkNUr1/WBQjYe6pk7KJ620thMauqDcGmvwDmtnzzOW E9BR5aZF33tKQjaqTGlclykyE+CcBF1rnce0YWB7nA6bH0gen68TNFciSn+eLT/v 6et3/6MwXAiwCgbX96ylQ0GilInmpnW8MwAPlBHycXy8l1g51DtLnnVPdZNZ9HhF gx9rnrI3BwNEoQ+FdjnfmtvAsagEf/ZNVIUJu5PgmZnrA4hbYWnQlKPkjsm6Moun xYhQFv62AosyU8x40aEkDRrOzJXsL5u6uf3t6+S4rh2cGdiG90Rc6D+PVKrXMhFB jehv2F0dVgv617CtWp+Z/Kw8UEMD4LRcffwin2/5IF6MKKSzpWdJlSOX6fTfDR0i cnOji9YYs0morx1Yl4QINqtr+iysP0ORU+bqRaRlNDPalg+yNdOsiFpQN1WzAzcO KIwrGg4kQ8a9JFs0anPnuJJrpN0DSiy5xrunxdrdHNcnjPeFEPSyCm0fH9hioQ9b lfvmcAjM3jRmsrycbef471but7xnVmWVTQkorD65ArjiZ3z5A4Y= =uEYC -----END PGP SIGNATURE----- --=-=-=-- --===============2064602771== Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: base64 Content-Disposition: inline X19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX18KZHJpLWRldmVs IG1haWxpbmcgbGlzdApkcmktZGV2ZWxAbGlzdHMuZnJlZWRlc2t0b3Aub3JnCmh0dHBzOi8vbGlz dHMuZnJlZWRlc2t0b3Aub3JnL21haWxtYW4vbGlzdGluZm8vZHJpLWRldmVsCg== --===============2064602771==--
