Deferred fastalpha behaves a bit better. Pulled over patch for https://jira.secondlife.com/browse/STORM-336 and https://jira.secondlife.com/browse/STORM-1011 from linden repo Sky rendered using new LL method. Assuming this fixes issues on AMD cards(works on cat 11.2) Added a few things missed related to spatial-parition updating. Added 'SkipReflectOcclusionUpdates' setting that prevents occlusion updates for reflection pass. Less taxing on CPU.
