Clippy lint griping:
I deliberately write redundant expressions so that the overall structure is more directly apparent.
```
result += data[x * 4 + 0];
result += data[x * 4 + 1];
result += data[x * 4 + 2];
result += data[x * 4 + 3];
```
I know that +0 doesn't do anything! I wrote it that way for a reason!
