Subject: Use linear filtering for ambient occlusion render target
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=702de88f837584fd046d787f7199e4560ceda9c4;hp=702de88f837584fd046d787f7199e4560ceda9c4;p=libs%2Fgl.git

Use linear filtering for ambient occlusion render target

The blurring step samples it exactly between texels so nearest filtering
may cause artifacts due to floating point math instability.
