KingSora/OverlayScrollbars

• Fixed the bug discussed in issue #59. (The scroll function synchronises now the DOM if needed)
• Fixed a iFrame bug in Chrome, if you dragged the scrollbar-handle while you moved outside the iFrame the mouse won't be bound anymore to the handle if you move back in and you released the mouse button in the meanwhile.
• In IE and Edge the plugin uses now screen coordinates instead of the page coordinates for the mouse position detection while scrollbar-handle-dragging, because the page coordinates are incorrect. (iFrame only)

JS

• fixed a bug which caused a invalid scroll position calculation of the .scroll() method if the direction of the target element was rtl
• in very rare cases the overflow-amount was calculated incorrectly
• sometimes the plugin was performing a full update, without it being required
• increased performance of the non-jQuery version

General

• I've created a FAQ page for the plugin
• The scrollbar-styling-guide is now enhanced due to #51

CSS:

• The basic themes doesn't use opacity anymore to make the handle color transparent, it uses now background: rgba() to achieve the same effect.
• Basic flexbox styles are now implemented

JS:

• The Extension system with the new methods OverlayScrollbars.extension(), .ext(), .addExt() and .removeExt().
• The initialization has now a new parameter which can be used to initialize OverlayScrollbars with a single or multiple Extensions
• Implemented #50 (clickScrolling enhancement if you press shift while clicking)
• Fixed #48
• Fixed a bug where the display property of the host-element wasn't detected properly.
• Firefox calculated sometimes false overflow values if the element was hidden during initialization
• The .scroll() method element options was changed. The axis property is now deprecated and its replacement is the new scroll property. This was done in order to provide the same functionality as the Element.scrollIntoViewIfNeeded() and the Element.scrollIntoView() method.
• A workaround in Firefox was implemented where scroll size was sometimes incorrect due to this bug.
• The .scrollStop returns now the current OverlayScrollbars instance so you can chain the method with other methods.
• The css transform: translate position for the scrollbar-handles is now in percent instead of pixels.

General:

• The documentation was enhanced with a article about flexbox.
• The documentation was enhanced with a article about extensions - with examples
• A download page for extension has been added to the website.

• Fixed #41
• Fixed #42
• Fixed a bug where async methods were executed even if the instance were destroyed
• Fixed a couple of iFrame bugs in InternetExplorer
• Added a new property in the return object of the getState() method called documentMixed. It indicates whether the host-elements document isn't the same document as the one with which the plugin was initialized. If this property is true it's most likely the host-element is inside a iFrame.
• AMD Support is back on track

Fixed #28

Fixed #25
Fixed a bug where the offset of the vertical scrollbar handle wasn't calculated properly.

I've rewritten the whole option handling. It's not possible to set invalid default options anymore.
The size of the plugin was reduced about 3-4kb in the minified versions.

Fixed #18

The calculated overflow Amount is now rounded to two decimals to prevent bugs in Internet Explorer and Edge.

Async image loads are now detected automatically. (beta)

The scroll method has been improved:
If you pass a element object with additional settings, the "block" property in the settings accepts now two new values: "center" and "nearest". It basically has now the exactly same capabilities as the scrollIntoView function.

Implemented #13
Fixed a bug where the plugin calculated incorrect scrollHeight if it was initialized to the body.
Fixed a bug where the plugin calculated incorrect scrollHeight if the host-element has auto-height.
