Feature-Request: Conditionally enable LazyLoad

Hi there,

I want to be able to conditionally enable/disable the lazy loading on my components - is this possible from within the the lazy load component?

E.g.:
I have CMS elements which can be used above or below the fold. I want to disable lazy loading above the fold and enable it below.

The solution I came up with is to double up on my render method:
```javascript
// Parent
render() {
return(
this.props.enableLazyLoading ? :
)
}
```

But it would be way cooler if I could wrap the render-output itself and just pass the prop.

Something like this:
```javascript
// MyComponent
render() {
return(

Super expensive Content

)
}
```

Any suggestions? Am I missing something? :)
