"Sublime Text 2" like scrolling with javascript / jQuery

Question

i'm trying to implement a Sublime 2 like scrolling bar with code preview in javascript / jquery.

Are there any plugins or code snippets out there which are trying to achieve the same?

Answer 1

I created a new project to do exactly this. It copies the content into an iframe and scales it down using css. So no canvas, no CORS issues and dimensions are correct.
