gatsby-plugin-image "fadeIn" equivalent?

[Eyas]

The old gatsby-image component had a boolean prop called fadeIn specifying whether or not the image should fade on load.

I am not seeing an equivalent for gatsby-plugin-image, am I missing something?

+1 on this

I also need to disable the fadeIn on my images and would like the option to be available for gatsby-plugin-image

Thank you
