It's not really known how this actually works. Some testing has shown that this probably performs no filtering, and common usage in games suggests it's not actually resizing the image at all.
However, this patch does seem to fix some homebrew showing quasi-duplicated images while still keeping other applications in a working state.

Not sure if this is a correct fix. Probably should instead change the decoding logic itself.

Both IA4 and IA8 had their component order mixed up. Additionally, IA4 used the wrong number of nibbles per texel. A4 skipped every second texel.

(not that it matters at the moment, because this code is not used yet)

We actually don't really know yet how the format is encoded. Hence just use what works.
