Is your feature request related to a problem? Please describe.

There were many strong api changes inside origin/wip-v3. Is there some roadmap for this branch to understand its development?
There were removed ProgramState::setTextureArray. And sampler2DArray support appeared. But as I properly understand this feature is used just to pass alpha channel now?

    if (desc.arraySize == **2**)
    {
        setPremultipliedAlpha(Image::isCompressedImageHavePMA(Image::CompressedImagePMAFlag::DUAL_SAMPLER));
        _samplerFlags |= TextureSamplerFlag::DUAL_SAMPLER;
    }
    else
    {
        setPremultipliedAlpha(preMultipliedAlpha);
    }

Is there plan to use it in general cases? Or there some api which I missed?
