Why isn't this using
{zoom: bucket.zoom + 1}
like we do insymbol_layout#addFeature
? That seems like the best match. @anandthakker understands that logic better than I do, though, I think.There was a problem hiding this comment.

Woah, good point @ChrisLoer. This raises an interesting issue. It's not just that we need to evaluate
text-size
with{zoom: bucket.zoom + 1}
during layout (though I think you're right about that) -- if text-size is zoom depentent, we also need to scale the icon at render time according to the current text-size value. And if text-size is a composite function, that's going to be problematic -- we could try to use the text-size attributes for the icon rendering pass in that case, but that would only help foricon-text-size: both
.In any case, I think this goes well beyond the scope of this PR. I'll ticket it separately, 👍 for now!
