Port Before/After Slider Control to jQuery

I have two implementations of a Before/After Slider control. See them below: This one is written in Three.js. I am satisfied with it. The code is all mine. [login to view URL] [Instructions: Hover you mouse over the top-right viewport, press Alt-w. The Slider control will be revealed] Here's the other one: [login to view URL] [It uses the Juxtapose library, and I need you to replace that code.] This is the behavior I want you to c-l-o-n-e: [login to view URL] Notice how the vertical bar completely disappears and the images become completely visible. I like that. You will put your code inside a library, with very clear instructions for future programmers to implement your wonderful creation. There is no real, solid deadline. I rather have quality work than work done in a hurry. You will get an "On Time" evaluation. I expect every file to be delivered on demand, even before the final product is ready. If you are the type of professional who believes on keeping some files, on not sharing your knowledge, please do yourself and me a favor: go click elsewhere, best of luck. Let me repeat this: I will not release one milestone unless the corresponding work (source files) are delivered, inspected and approved. I wish the Freelancer website made that obvious requirement clear. -Ramon F. Herrera JFK Numbers
