| * This library encodes arrays of bits (whose size need not be a multiple of 8 | |
| * bits) as arrays of 32-bit words. The bits are packed, big-endian, into an | |
| * array of words, 32 bits at a time. Since the words are double-precision | |
| * floating point numbers, they fit some extra data. We use this (in a private, | |
| * possibly-changing manner) to encode the number of bits actually present | |
| * in the last word of the array. | |
| * </p> | |
| * | |
| * <p> | |
| * Because bitwise ops clear this out-of-band data, these arrays can be passed | |

| * @description | |
| * <b>Use sjcl.random as a singleton for this class!</b> | |
| * <p> | |
| * This random number generator is a derivative of Ferguson and Schneier's | |
| * generator Fortuna. It collects entropy from various events into several | |
| * pools, implemented by streaming SHA-256 instances. It differs from | |
| * ordinary Fortuna in a few ways, though. | |
| * </p> | |
| * | |
| * <p> | |
| * Most importantly, it has an entropy estimator. This is present because | |
| * there is a strong conflict here between making the generator available | |
| * as soon as possible, and making sure that it doesn't "run on empty". | |
| * In Fortuna, there is a saved state file, and the system is likely to have | |
| * time to warm up. | |
| * </p> | |
| * | |
| * <p> | |
| * Second, because users are unlikely to stay on the page for very long, | |
| * and to speed startup time, the number of pools increases logarithmically: | |
| * a new pool is created when the previous one is actually used for a reseed. | |
| * This gives the same asymptotic guarantees as Fortuna, but gives more | |
| * entropy to early reseeds. | |
| * </p> | |
| * | |
| * <p> | |
| * The entire mechanism here feels pretty klunky. Furthermore, there are | |
| * several improvements that should be made, including support for | |
| * dedicated cryptographic functions that may be present in some browsers; | |
| * state files in local storage; cookies containing randomness; etc. So | |
| * look for improvements in future versions. | |

| // | |
| // jQuery Versions - jQuery 3.x. Although script should work from jQuery 1.1 and up but no promises are made. | |
| // Browsers Tested - See jQuery browser support page: https://jquery.com/browser-support/. Only modern | |
| // browsers are supported. | |

| // 2.2.0 - (2018-05-16) No changes to RC1 | |
| // 2.2.0-rc.1 - (2018-04-28) Merged resize sensor to find out size changes of screen and | |
| // again little bit tuned this to support more npm goodies. | |
| // * Merged: | |
| // - #361 Event based reinitialising - Resize Sensor | |
| // - #359 Use npm scripts and local dev dependencies to build the project | |
| // 2.1.3 - (2018-04-04) No changes from Release Candidate 2 so making release | |
| // 2.1.3-rc.2 - (2018-03-13) Now using 'script/jquery.jscrollpane.min.js' main | |
| // in package.json rather than 'Gruntfile.js' | |
| // 2.1.3-rc.1 - (2018-03-05) Moving Gruntfile.js to root and example HTML | |
| // to subdirectory examples | |
| // 2.1.2 - (2018-02-16) Just on console.log remove and Release! | |
| // This version should play nicely with NPM | |
| // 2.1.2-rc.2 - (2018-02-03) Update package.json main-tag | |
| // 2.1.2-rc.1 - (2018-01-18) Release on NPM. | |

| // 2.1.1-rc.1 - (2017-12-23) Started to slowly merge stuff (HO HO HO Merry Christmas!) | |
| // * Merged | |
| // - #349 - ScrollPane reinitialization should adapt to changed container size | |
| // - #335 Set drag bar width/height with .css instead of .width/.height | |
| // - #297 added two settings: always show HScroll and VScroll | |
| // * Bugs | |
| // - #8 Make it possible to tell a scrollbar to be "always on" | |
| // 2.1.0 - (2017-12-16) Update jQuery to version 3.x | |
