Subject: fixed bug in portal culling code that allowed a leaf to be revisited multiple times... 
X-Git-Tag: xonotic-v0.1.0preview~3472
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=f707812826e0794fa7737bb5596a29bebf649026;p=xonotic%2Fdarkplaces.git

fixed bug in portal culling code that allowed a leaf to be revisited multiple times, causing it to be counted multiple times, and wasting a small amount of time marking surfaces redundantly
