- Implemented scroll snapping at the end of a middle-mouse-button scroll.
- As this scrolling occurs within chrome Javascript, chrome-only DOM methods
had to be added: window.MozScrollSnap and element.MozScrollSnap
- Bug 1137937 tracks implementation of a replacement for these chome-only DOM methods,
to be replaced with a web accessible API.
- Added new WebIDL dictionary, ScrollToOptions. This dictionary extends
ScrollOptions by adding "left" and "top", specifying the scroll offset.
This will be later extended with more members to allow scroll offsets to be
specified with logical axes.
- Implemented Window.Scroll, Window.ScrollTo, Window.ScrollBy, Element.Scroll,
Element.ScrollTo, and Element.ScrollBy functions that accept ScrollToOptions
as a single parameter.
- Removed ScrollOptions dictionary parameter from existing Window.Scroll,
Window.ScrollTo, and Window.ScrollBy functions as these have been replaced
with functions accepting a single parameter, ScrollToOptions.
- Added new WebIDL dictionary, ScrollIntoViewOptions. This dictionary
extends ScrollOptions by adding "block", specifying whether the element
start or end will be scrolled into view.
- Replaced Element.ScrollIntoView(bool,ScrollOptions) with
Element.ScrollIntoView(ScrollIntoViewOptions) to match updated
CSSOM-View scroll-behavior specification.
- Extended the Element and Window webidl interfaces as described in the
CSSOM-View smooth-scrolling specification.
- The Element.scrollTop and Element.scrollLeft changes have been omitted
until either WebIDL is extended to allow properties to have union datatypes
that contain dictionaries or the CSSOM-View smooth-scroll specification
is upddated. This will not prevent the other interface changes from being
useful.
- Implemented wrapper functions for the nsGlobalWindow to connect to the new
WebIDL bindings. The ScrollOptions parameters are ignored in this patch,
and used in Part 3 of this patch series.

This patch adds the WebIDL definitions and implementation of
getAnimationPlayers on Element.
It does not include the full definition of AnimationPlayer but only readonly
versions of the currentTime and startTime attributes since these are easy
to implement and enable identifying the different animations that are returned
for the sake of testing.
Web Animations defines getAnimationPlayers as only returning the animations that
are either running or will run in the future (known as "current" animations).
This will likely change since it seems desirable to be able query animations
that have finished but are applying a forwards fill. For now, however, this
patch makes us only return animations that have not finished.
This patch also removes an assertion in ElementAnimation::GetLocalTime that
would fail if called on a finished transition. This assertion is no longer
necessary since an earlier patch in this series removed the overloading of
the animation start time that meant calling this on a finished transition
was unsafe. Furthermore, this assertion, if it were not removed, would fail
if script holds onto a transition and queries its start time after it
completed.
The reflow-on-zoom behavior needs a more robust determination of the font size inflation, so
that it can adjust its behavior depending on whether font size inflation has been
enabled for a given element's text. This patch also modifies the behavior of reflow-
on-zoom such that it will zoom in to piece of text, with reflow, if the minimum
specified font size in the font size inflation preferences is greater than the
current font size, with font size inflation, of the element.
