Fixes #627 by adding direction to the overscanIndicesGetter

[bvaughn]

Mind updating the docs as well to list the new parameter? 😄

[offsky]

Like that?

Thanks, but not quite. Update the section below that the hyperlink refers to (#overscanindicesgetter)

Im sorry, I dont understand. Im happy to make a change if you can elaborate.

I was just clarifying that- by enabling horizontal scrolling- you're using List in a way it's not intended to be used. It's great that everything works (excepting this). I just wanted that clarification.

The reference I made about width being 100% is here.

Brian, I think we got our conversations mixed. This pull request is for my upgrade to the overscanIndicesGetter. Your last comment seems like it was meant for issue #630. Im happy to update this pull request with better documentation if you can elaborate on what changes you want me to make.

[bvaughn]

lol yes sorry. I was responding via email client and I assumed your response was to my most recent comment on the issue. Sorry!

Go look at the Grid props docs. Specifically, the overscanIndicesGetter property doesn't defines its interface inline b'c it's hard to read. Instead it links to a separate section. I was requesting you put the interface/params list there. This is similar to how other props (eg cellRenderer) are done. 😄

👍 Thanks
