Extension:RevisionSlider

This extension adds a slider interface to the diff view, so that you can easily move between revisions.

Usage
Compare two revisions of a page by selecting them on the history page. The RevisionSlider will load and show at the top of the diff screen.
 * Each bar represents a revision.
 * Bars to the top show growth of the page, bars to the bottom show a reduction of size.
 * Hovering over bars shows more details such as the edit summaries and authors.
 * The colored pointers can be used to select and compare certain revisions.
 * They can be moved by dragging them with the mouse or clicking on a bar.
 * The arrow-bars at the side are used to navigate through the revision history and show older and newer revisions.

Limitations
The current version is limited to only load the last 500 revisions of a page. The RevisionSlider will not load when comparing revisions beyond the 500 and it is also not possible to scroll beyond the 500th revision.

Background
The RevisionSlider is a feature to fulfill one of the top wishes of the German Community wishlist and is developed by WMDE's TCB team. It is inspired by DerHexer's revisionjumper gadget and based on a prototype by the WMF Community Tech team.
