[css2.1] Gamma section still there

Hello,

My apologies for bringing up a CSS 2.1 issue, but this one is at least straightforward, easy to resolve (as we already resolved it for another spec), and affects no tests at all.

CSS3 Color used to have a gamma section, 3.1.1 [1] which following a comment from Chris Murphy in 2008 and follow-up comments from David Baron and Dave Singer was wisely removed [2] because it was outdated (SGI workstations, really?), incorrect (failed to note the change of system gamma from MacOs 10.6 onwards), and misleading (could be interpreted to mean performing gamma processing in addition to color management).

OK, so far so good. The exact same text that was pulled, though, is in CSS 2.1 in section 14.3 [3]. The good news is that it is all a non-normative note. The bad news is that it is still outdated, incorrect and misleading.

My proposal to fix this issue, and bring CSS 2.1 in line with CSS3 Color is therefore to remove the entire non-normative section (the  heading, pointer to the PNG spec for gamma, and the note). This is the exact same fix we already did in CSS3 Color.
