Feature Request: options for webp and traced svg

[TestPlan]

I'm using the plugin and I'm not seeing a way to use the traced svg or webp options. Those are really nice features that come with gatsby-image. Is there a plan to add more options?

Great suggestion. Will do.

Why doesn't gatsby-transformer-sharp pick up these images? Would be nice if we could do queries on featuredImage like you can in gatsby-source-wordpress.

childImageSharp {
  fluid(maxWidth: 1200) {
    ...GatsbyImageSharpFluid_withWebp
  }
}

You can. The solution for making it work is in #3
