1px anti-aliased line with dashes is near-solid

[NinthDesertDude]

All line sizes except 1px have clear gaps for an anti-aliased line, but at the 1px size, the anti-aliased line isn't very helpful:

In some cases like with the pure dotted line, it actually eliminates dotting entirely. I'd consider this surprising behavior:

The problem is, it wouldn't be great to stop respecting anti-aliasing since the lines can be curving and you would have no replacement for 1px dashed AA lines to anyone who wants it. So I'm not actually sure what the solution is, except specially handling single-pixel lines to be drawn without anti-aliasing only if straight. But that still feels hacky. Just giving this feedback in case it's useful
