| * @forked from http://css-tricks.com/snippets/jquery/draggable-without-jquery-ui/ | |
| * @changes | |
| * -- Unline original, only x-direction movement permitted, since intended for a video or timeline scrubber. | |
| * -- Correctly unbinds dragging in situation where user begins dragging, moves the mouse off the timeline, and then releases the mouse. | |
| * -- Refactored for DRYer and easier reading. | |
