Add the ability to scroll

[fivestones]

I know there's no interface to scroll with on the chromecast itself, but it'd be great if there was an option in castdeck that would add javascript scroll messages to the chromecasted page so it would scroll at the user-defined speed from top to bottom (or maybe down and back up over and over?)

Hi, thanks for your interest in castDeck! It's a nice idea and I can see some use cases:

1. scroll the client based on user input from castDeck itself
2. scroll the client automatically, based on timing

The main problem with this is cross site scripting. Since the user application is displayed in an iframe, I cannot get any message into it without also adding some scripts to the user application itself (using postMesage or websockets). If you start doing that, you might just as well implement the entire scrolling behaviour into the user application

This is what I do for my own purposes, which is displaying a (potentially long) competition schedule. That page automatically scrolls with time and centers the current participant in the viewport. With this approach, use case 2 vanishes.

Use case 1 may be interesting though.

I'll keep this issue open for now. I am kinda pressed for time, but if I can spare some time in the next few weeks, i'll give it a go
