Subject: Multisampling initialisation moved from vid_sdl to gl_backend. Make cubemaps array... 
X-Git-Tag: xonotic-v0.6.0~163^2~399
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=e272f5efe910b09242dd42c4044aa85bfe9b1710;p=xonotic%2Fdarkplaces.git

Multisampling initialisation moved from vid_sdl to gl_backend. Make cubemaps array dynamic (segments are allocated on load), this uses less memory, and MAX_CUBEMAPS was raised.
