The idea behind the clamps is that the fixed function pipeline is generally limited to the [0.0;1.0] range. bbf313e7 added a test for that, and there was e.g. 14706 (which doesn't contain much info tbh).
Personally I'd keep the clamps in unless a test says otherwise or there's another compelling reason to remove them. But since it is quite unlikely to matter that's not a strong opinion. The ideal solution is of course to write a test. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.20 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBAgAGBQJSJciCAAoJEN0/YqbEcdMwQ2gP/Ayrnyv1b7VmviOCBLdKpW3P YjEgLSFtaiEMGjJ6DD3iTLTRBaMOWZIryKyXdE5QLecKx35xuk6GbC+OAXgCCZfU a558nJwymMtMpiU9Wa2nuUXF4p+KuC8CHkCgfOGF1D4wDZcQQxfEcvKcwAGPaZwV PWiKKI8SWO69XlawZHOLyWz97gghYpLrHIexOxbCVXGMXee7pqAQTSz2oRVppHot 39T2qbFo21qtoyK7sgqMgnRko52eiJGSBVHCfcfhhMPh+mksQvPoZDcdK/KSAl6r K5Py0kbVjBDjE9I6uCGO9+bt6a6RrJpC/6JGIOypDvicnjd/7X4LK8SYfGv3Cvr6 qejlsAouxrQgdYARrdjnoR4IEK8WviBzOZDnvxOS8dlEsJxjMjxIScnemdNacNKO QY3DJ/GmfnsnOXnrrvADKkLvCkeIUCE5v6U9Kv+S9GsMgNeJs1IEHzQpROBmt/iO ukUH+aOe4JReH1mtynrX+GsjwZkDPzatx48SxOOopWW5akiCbEsJNFirR4m1St9E 5+iOCkGQkjWVz95XgZt3VRpUBxx12JHsX1/UscBmprvkutmbUOYvRIpgqdTyZknD dW4x79KWQ6YUu3k8Lho8EfChR8rzPoDeaHwclY/WrwE+yuHugk+z0dv/gclC3eiL HAQ0T8GuuElJvdPfgE3F =8XAf -----END PGP SIGNATURE-----
