commit d8eb7287fe82e74da8f2938e7190610d3ded0051

    i965: Faking the ETC2 compression on Gen < 8 GPUs using two miptrees.

    GPUs Gen < 8 cannot sample ETC2 formats. So far, they converted the
    compressed EAC/ETC2 images to non-compressed RGBA images. When
    GetCompressed* functions were called, the pixels were returned in this
    RGBA format and not the compressed format that was expected.

    Trying to fix this problem, we use a secondary shadow miptree to store the
    decompressed data for the rendering and the main miptree to store the
    compressed for the Get functions to work. Each time that the main miptree
    is written with compressed data, we decompress them to RGB and update the
    shadow. Then we use the shadow for rendering.
