The way it works in dwrite right now, which is how it works in harfbuzz I took this from:

```
foreach feature in features
    foreach lookup in feature.lookups
    {
        for first subtable that matches -> apply this subtable and return
    }
```

So, it shouldn't skip lookups after some lookup was applied, it should skip subtables after first match, but still iterate through all lookups. That's a major difference.
