        The "webkit" property on the window was not getting installed for subsequent
        loads due to intricate dance playing setting the JSDOMWindow where the DOMWindow
        object is not yet in a Frame when the JSDOMWindow is created. Since we were
        adding the "webkit" property on construction, the property was returning null
        thinking it had no Frame and was in a bad state. We can fix this by making the
        "webkit" property behave like all the other window properties moving its getting
        to JSDOMWindow::getOwnPropertySlot.

        Added API test (WebKit2Cocoa/UserContentController).

        Turn width/height to presentation attributes
        https://bugs.webkit.org/show_bug.cgi?id=135046

        Reviewed by Dean Jackson.

        The elements <svg>, <image>, <pattern>, <mask> and <foreignObject> have the
        'width' and 'height' attributes. So far they can just be set by SVG DOM or
        setAttribute. Furthermore, animations just work with SVG Animation - No support
        for CSS Animations and CSS Transitions. We started to turn the width and height
        attributes on SVG roots to presentation attributes already. A presentation
        attribute is a CSS property that can also be set by DOM (or now by SVG DOM).

        This patch turns all width and height attributes to presentation attributes. It
        basically allows authors to style width and height with CSS as well. Width and
        height can now be set with CSS style sheets and can be animated with CSS.

        To some degree it made it possible to remove code duplication. However, since
        SVG DOM requires us to use SVGLength types and since we did not turn all
        SVG attributes to the CSS length values (and our internal Length struct) yet,
        we still need a hybrid - a bridge between SVGLength (for SVG DOM) and Length (for
        RenderStyle). Once we move all attributes to use the Length struct, we can make SVGLength
        a wrapper for Length and can move more code to the render tree.

        The current challenge is to synchronize SVG DOM, normal DOM and RenderStyle.
        With this patch we handle most part in RenderStyle. SVG DOM changes are
        synchronized to DOM and RenderStyle will call needsStyleRecalc. Furthermore,
        SVG Animations will continue to animate the SVG DOM (and synchronize the changes
        back to RenderStyle) if the element has a JS property for the currently animated
        attribute.

        Short example:

            <rect>
                <animate attributeName="width">
            </rect>

        The <rect> element has the SVG DOM property 'width'. Therefore, we animate the SVG DOM
        property and synchronize RenderStyle.

            <ellipse>
                <animate attributeName="width">
            </ellipse>

        The <ellipse> element does NOT have the SVG DOM property 'width'. Therefore, we
        animate the CSS property directly. With synchronizing RenderStyle in all cases, we
        make sure that the CSS cascade works even on animating on multiple SVG hierarchy
        levels (animation of 'width' on <g> and inheriting the property value on a child
        <rect>).

        With using presentation attributes, we also inherit the CSS property parsing for
        SVG attributes. <rect width="  100px  "> is possible now. (Note the trailing whitespaces.)
        This follows a recent resolution of the SVG WG.

        Since we turned width and height to presentation attributes, the layout optimization
        selfHasRelativeLengths() in the DOM can't be used anymore. selfHasRelativeLengths() was
        intended to solve a problem where we did not layout relatively position/sized elements
        when the parent changes its size. However, as a side effect it did not call layout
        for absolutely positioned/sized elements since the layout does not change. I run
        all performance tests that we have and even wrote a test with hundreds of elements
        that would be affected by this optimization. The differences were inside the sigma
        of a normal test run. (Means I couldn't measure a performance difference.)
        Therefore, it is not worth it to keep the "optimization" around and I will probably
        remove it entirely for all basic shapes but <path> and <polygon> in future patches.

        [MSE] YouTube video decode error when variant-switching
        https://bugs.webkit.org/show_bug.cgi?id=135128

        Reviewed by Brent Fulgham.

        Test: media/media-source/media-source-overlapping-decodetime.html

        When variant-switching, the situation can arise where an existing sample with a presentation
        timestamp of N and a decode timestamp of M, and a new sample with a presentation timestamp > N
        and the same decode timestamp of M, will keep the new sample from being added to the SampleMap.
        This can result in a decode error when samples depending on that new, missing sample are enqueued.

        The MSE spec is silent on the issue of overlapping decode timestamps. However, it guarantees that
        presentation timestamps are non-overlapping. So instead of using just the decode timestamp as a key
        for storing the samples in decode order, use both the decode timestamp and the presentation timestamp.
        That ensures that samples with different presentation times but equal decode times are both inserted
        into the decode queue, and in the correct order.

        After r166117 all layer flushing starts on the root frame; we no longer flush layers
        for each frame during painting. However, flushing GraphicsLayers can set some state
        on a subframe RenderLayerCompositor that is now never processed, which breaks scroll
        layer registration.
        
        Fix by doing a walk of the Frame tree, and calling didFlushLayers() on subframe RenderLayerCompositors
        before calling didFlushLayers() on self.

        Reviewed by Darin Adler.

        We currently pass a SharedBuffer wrapped in WebCoreSharedBufferData to ImageIO for image
        decoding. This is not thread safe since ImageIO will access this buffer on a separate
        thread. We access SharedBuffer::buffer() on the other thread which resizes the Vector
        m_buffer if m_size is greater than the vector size. Since the code in SharedBuffer::append()
        sets m_size before appending the data to the buffer, m_size is out of sync with the m_buffer
        size for the entire duration of the Vector append which could be doing a lot of copying if
        the resource is large. While this change does not fix the race condition, we can at least
        reduce the chances of SharedBuffer::buffer() calling resize() by setting m_size after the
        cector has finished appending.

        REGRESSION (r169105): Crash in selection
        https://bugs.webkit.org/show_bug.cgi?id=134303

        Reviewed by Ryosuke Niwa.

        When splitting the selection between different subtrees, all subtrees must have their selection cleared before
        starting to apply the new selection. Otherwise, when selecting objects in a named flow thread and going up
        its containing block chain, we can end up in the view's selection root, which has not yet been updated and so
        we get inconsistent data.

        To achieve this goal, the selection update was split into a "clear" and an "apply" method. The updateSelectionForSubtrees
        method first iterates through all subtrees and performs the "clear" method and then starts all over again
        and performs the "apply" method.

        Also, the selectionStart/End members in RenderView have been renamed to fix problems caused by the fact that
        RenderView inherits SelectionSubtreeRoot, which also has the same selectionStart/End members.

        [MSE] Re-enqueue after a removeCodedFrames() only if the removed frames overlap what may have possibly been enqueued but undisplayed.
        https://bugs.webkit.org/show_bug.cgi?id=135039

        Reviewed by Eric Carlson.

        When a client calls removeCodedFrames(), we must re-enqueue those ranges if the removed samples overlap with
        enqueued but possibly un-displayed samples. Otherwise, replacement samples may lead to decode errors as those
        new samples dependencies are not met. But if we re-enqueue too frequently, this may cause subtle but noticible
        display timing glitches, so only re-enqueue when removeCodedFrames have a possiblity of removing enqueued, but
        not yet displayed samples.

        CSP: Drop 'script-nonce' directive.

        This patch drops the outdated 'script-nonce' Content Security
        Policy directive. It was removed from the spec, and replaced in
        CSP2 with a new 'script-src' syntax. We should implement that
        instead.

        Until then, removing the outdated syntax will ensure that no one
        ends up relying on it in WebKit's implementation.

        This should have limited web-visible impact, as the feature is
        behind the CSP_NEXT flag, which is not enabled by default.

        <rdar://problem/16088789>

        Reviewed by Benjamin Poulain.

        When individual elements inside an overflow:scroll with -webkit-overflow-scrolling: touch
        had touch event listeners, we would fail to take the scroll offset into account when
        building the touch event region, causing touches on those elements to fail after scrolling.
        
        Touch event region building uses RenderObject::absoluteClippedOverflowRect(), and that
        code path tries to fix up repaint rects to work correctly in composited overflow:scroll.
        However, that broke the touch region computation.
        
        Fix by only ignoring the scroll offset for calls to computeRectForRepaint() which
        have a non-null repaintContainer (which indicates that we're doing a repaint in the
        compositing layer), and for which the repaintContainer is the containing block
        which is using composited scrolling. This restores correct behavior to the event region
        code which always calls this with a null repaintContainer.

        This patch implements sparse mode for auto-placement algorithm, which is

        auto-placement cursor in
        RenderGrid::placeAutoMajorAxisItemsOnGrid() and updates it accordingly
        when auto-positioned items are placed.
        If we're in dense mode it resets the cursor after each item (which keeps
        the old behavior that was using dense mode by default).

        GridIterator has been adapted to look for empty areas from a given

        The paginatedAndComposited bit being set in updateLayerPositions just didn't work, since compositing states
        can change without triggering that function. This patch just gets rid of the bit and does a crawl every time
        to check. This ensures that changes in compositing states don't necessitate any changes in pagination,
        since the lookup will always check the current compositing state.
        
        The new function that does this check is hasCompositedLayerInEnclosingPaginationChain.

        - polyline or polygon element with no point data (points attribute missing or empty)

        To achieve this a method (isRenderingDisabled) was added to RenderSVGShape and it's derived classes.
        This is used to determine if an element is included when creating the union of child bounding boxes
        in a container element.

        Unlike containsUncommonAttributeSelector(), selectorListContainsUncommonAttributeSelector() does not
        evaluate the attribute for "uncommon" types.

        It would be possible to change the function instead to evaluate common attributes based
        on the match type and the pseudo class type. Such change would be more risky
        and we would get very little benefit from it, I leave that for later if that ever becomes useful.

        http/tests/media/media-source/mediasource-play.html

        The primary change necessary to fix the mediasource-duration.html test was to add support
        for delaying the completion of a seek operation until the HTMLMediaElement's readyState
        rises to > HAVE_CURRENT_DATA. This is accomplished by modifying MediaSourcePrivate to have
        waitForSeekCompleted() and seekCompleted() virtual methods. These are called by MediaSource
        when a seek operation results in the current time moving outside the currently buffered time
        ranges, and when an append operation results in the readyState changing, respectively.

        A number of other drive-by fixes were necessary to get this test fully passing, as noted
        below.

        Make the MediaSource the primary owner of the media's duration, rather than the MediaSourcePrivate.
        Move the MediaSourcePrivateClient pointer to the MediaSourcePrivate from the MediaPlayerPrivate, so
        the MediaSource's duration can be retrieved.  While we're at it, do the same thing for buffered.

        Previously, RuleSet was partitioning each rule based on the rightmost filter.
        While fast, this had the side effect of putting many selectors with ID match in the class
        bucket (because the selectors are generally written starting with the ID).

        This patch replace the code of findBestRuleSetAndAdd() by a simple loop going over all

        We first loop over all the CSSSelectors related by SubSelector, this correspond to the rightmost fragment.
        If a filter with high specificity is found, we add the rule immediately and end there.
        If a filter that is not very specific is found, we keep a pointer to the selector to use it later.

        [CSS Grid Layout] Update grid-auto-flow to the new syntax
        https://bugs.webkit.org/show_bug.cgi?id=134057

        Reviewed by Sergio Villar Senin.

        In last versions of the spec grid-auto-flow syntax has changed. New
        syntax is:
        [ row | column ] && dense? | stack && [ row | column ]?

        Implemented parsing for new syntax and added/modified test cases in
        current layout tests.

        For the moment, the implementation keeps working in the same way, but
        using "stack" value for grid-auto-flow property instead of "none". This
        should be fixed in a follow-up patch once "stack" is properly
        implemented.

        Also "dense" needs to be reviewed. Right now auto-placement algorithm is
        always "dense" and never "sparse".

        [MSE] Overlapping appended ranges must cause the decoder to flush and re-enqueue.
        https://bugs.webkit.org/show_bug.cgi?id=134805

        Reviewed by Eric Carlson.

        When appending a range of media data which overlaps with an existing range, SourceBuffer
        must cause the decoder to flush and re-enqueue samples. Those samples removed by appending
        the overlapping range may have already been enqueued for display, and unless the decode
        queue is flushed, corruption or decode errors may occur as the new samples are enqueued for
        display.

        Add a boolean flag onto TrackBuffer to indicate whether the decoder needs to be flushed and
        re-enqueued the next time an append operation completes. Set this flag whenever samples are
        removed due to overlapping or an explicit call to removeCodedFrames(). Move the contents of
        sourceBufferPrivateSeekToTime() (which previously did flushing and re-enqueueing) into a new
        function, reenqueueMediaForTime(), which can be called from sourceBufferPrivateAppendComplete().

        Drive-by fix: findSyncSampleAfterDecodeIterator() would return the passed in iterator if that
        sample is a sync-sample. Fix this to correctly return the next sync sample.

        Drive-by fix: Use a SampleMap, rather than a DecodeOrderSampleMap, to track erased samples

        [Curl] Cache entry invalidated too early.
        https://bugs.webkit.org/show_bug.cgi?id=134681

        Reviewed by Alex Christensen.

        When a cache entry has expired, it is invalidated when a request for the corresponding url is started.
        This is too early, since the resource is possibly not modified (even though it has expired),
        and the server might respond with a 304 (not modified) response.
        When we then receive a 304 response, the cache entry is deleted, and we have no cached response/data to provide.
        This can be solved by not invalidating the entry when a request for that url is started,
        but instead invalidate when a 200 OK response is received (which means the resource has been modified).

        (WebCore::CurlCacheManager::isCached): Avoid invalidating cache entry when it has expired, wait until we know the server response.

        CSS canvas color parsing accepts invalid color identifiers

        Reviewed by Benjamin Poulain.

        Current implementation of the CSSParser::parseSystemColor assumes
        that if a valid cssValueKeywordID is got then it has to be a valid
        color. Such assumption is wrong and lead to many bugs and layout
        test failures.

        The parseSystemFunction determines now whether the parsed color is
        valid or not.

        Addtionally, a new method has been added to share the logic of
        determining whether a CSSValueID is a valid primitive values for
        colors or not. Generally, we should avoid passing invalid color
        identifiers to the theming API.

        [iOS] caption size is sometimes incorrect in fullscreen
        https://bugs.webkit.org/show_bug.cgi?id=134740

        Reviewed by Jer Noble.

        Captions on iOS are displayed in fullscreen with a TextTrackRepresentation object. Because
        the fullscreen video presentation is controlled by code in the UI process running on the
        UI thread, WebCore is notified of changes to fullscreen state asynchronously. This resulted
        in the TextTrackRepresentation object being created and/or destroyed too late some of the 
        time, which caused us to sometimes display captions incorrectly. Fix this by setting up and
        tearing down the TextTrackRepresentation object when WebCore's 'webkitfullscreenchange'

        DOMWindows should register themselves with the GamepadManager when they have event listeners

        By having DOMWindows register with the GamepadManager when they have/don’t have gamepad event
        listeners, we accomplish two things:

        Ensure we compute the height of replaced elements to 'auto' when appropriate.
        https://bugs.webkit.org/show_bug.cgi?id=134700

        Reviewed by David Hyatt.

        This fixes two issues:

        1) If a replaced element has a percentage height specified then its
        height should compute to 'auto' when its containing block does not
        have a height 'specified explicitly'. We were taking this to mean when
        its containing block's specified height value is 'auto' - in fact it
        means when the containing block's computed height is auto.

        2) Top and bottom on the containing block should only affect the
        height of the block if that block has absolute or fixed position.

        This brings us into line with IE, Firefox, and Chrome.

        Reviewed by Darin Adler.

        This patch removes 2 integral roundings from InlineFlowBox:
        1. Border and padding sizes are implicitly integral truncated by the 'int' return type
           of borderLogicalLeft/Right()/paddingLogicalLeft/Right(). It results in losing
           fractional border/padding values.
        2. Painting rectangle is explicitly rounded which pushes border and
           other decoration elements to odd device pixel positions on retina displays.
        These values get pixel snapped right before calling in to GraphicsContext::*.

        There was a fair bit of overhead when calling Node::ensureRareData()

        We were not inlining ~QualifiedName() and it was showing up in some

        This patch modernizes QualifiedName a bit by using RefPtr to store

        [iOS] [Media] Prevent page zoom if it started in the video element

        <rdar://problem/16630794>

        Reviewed by Sam Weinig.

        In r170572 I attempted to prevent the page zoom from happening
        when the user was attempting to fullscreen the video. That fix was
        not complete, because it relied on the touchstart event being
        sent before a gesture event. It turns out this doesn't always happen,
        so we need to apply the same check in the gesture event - if the
        gesture began with two fingers on the media, don't do a page zoom.
        The exception is zooming out, if you've managed to make the video
        cover the entire screen (also, the pinch-out-of-fullscreen gesture
        does not get handled by WebKit).
