Fixing Disappearing Texture Alpha Details in MipMaps

I guess this could be fixed by changing the refValue depending on the mip-level generated without incurring cost there. Another approach might be using a slightly larger downsampling kernel, kind of like (1 3 3 1)^2, or some other more bicubic-like variant (as this will likely be similar in effect to max, but possibly more well-behaved for iterated application). (1 3 3 1)^2 would have a sum of 64, so could be computed without divisions (and even without multiplications) likewise.[/quote]
