        (-[DOMRange renderedImageForcingBlackText:renderedImageForcingBlackText:]):
        Scale the NSImage size by the device scale factor,
        similar to what we did for drag images in r167403.
        Ideally this scaling would happen in the code that
        generates the images, but this is a much larger change
        with much more regression potential.

        REGRESSION: Search highlight is broken in RTL multicolumn content
        https://bugs.webkit.org/show_bug.cgi?id=135452

        Reviewed by Simon Fraser.

        The offsets for elements inside RTL multi-column elements are incorrectly computed because
        the columns don't calculate their left position according to the writing direction.

        The patch extracts the column position computation in two helper functions (for top and left)
        so they can be used when needed in different parts of the code. In our case, the |columnLogicalLeft|
        function should be used inside |columnTranslationForOffset|.

        Eliminate "FractionConversion" from CSSPrimitiveValue::convertToLength
        https://bugs.webkit.org/show_bug.cgi?id=135377

        Reviewed by Darin Adler.

        The FractionConversion argument in CSSPrimitiveValue::convertToLength
        doesn't seem to actually have a purpose. It is for converting numbers
        into Length(x * 100, Percent), but this case shouldn't be reachable.
        The original patch introducing it doesn't shed any light either:
        [https://bugs.webkit.org/show_bug.cgi?id=74913

        This patch removes the now unused FractionConversion argument. Note
        that we can probably also merge the two Fixed conversions, as the
        two only differ in clamping large numbers (probably unintended).

        Web Inspector: console.profile missing profile information

        Reviewed by Timothy Hatcher.

        By switching console.profile to start/stop the timeline we would
        not have a chance to recompile JS functions with profiling information.
        This used to work because whenever the inspector was open we would
        have profiling information enabled. Go back to that behavior.

        Refactor EventHandler to call ScrollAnimator::handleWheelEvent for overflow scrolling
        https://bugs.webkit.org/show_bug.cgi?id=135195

        Reviewed by Beth Dakin.

        ScrollableArea::handleWheelEvent is not currently being used to handle wheel events for overflow scrolling; it instead directly invokes ScrollableArea::scroll.
        In order to expose wheel phases on Mac, the PlatformWheelEvent itself should propagate down to ScrollableArea, not just the scroll granularity, direction and
        multiplier required by ScrollableArea::scroll. With this patch, PlatformWheelEvent will be "shipped" along with the WheelEvent.

        No new tests, since behavior should not have changed.

        [iOS] REGRESSION(r171526): PDF documents fail to load in WebKit1 with disk image caching enabled
        https://bugs.webkit.org/show_bug.cgi?id=135359
        <rdar://problem/17824645>

        Reviewed by Darin Adler.

        r171526 broke the case where we have a memory mapped file from the DiskImageCache in the
        SharedBuffer. In such a case, m_buffer is empty and createCFData() returned an
        WebCoreSharedBufferData with an empty buffer.

        Fix this by taking the easy route of bringing back the old code for the disk image cache
        file backed case. In the long run we probably want to remove the iOS specific disk image
        cache anyway.

        Review also uncovered another bug in r171526 where we were balancing an Objective-C alloc
        with a CFRelease which is incorrect when running under GC. Fix that by using adoptNS along
        with adoptCF which is what the code did before.

        REGRESSION (r160806): CSS zoom property doesn't work on anything inside anchors.
        <https://webkit.org/b/135344>
        <rdar://problem/17759577>

        When DeprecatedStyleBuilder applies the CSS zoom property (ApplyPropertyZoom)
        it first resets the "effective zoom" by calling RenderStyle::setEffectiveZoom().

        This mechanism was not resistent to being called multiple times, due to the
        optimization in RenderStyle::setZoom() to avoid copy-on-writing the shared data
        when setting some property to the already-set value.

        The bug would happen in this sequence:

        ApplyPropertyZoom:
            - setEffectiveZoom(1);
            - setZoom(2); // this updates the effective zoom
        ApplyPropertyZoom:
            - setEffectiveZoom(1);
            - setZoom(2); // this doesn't update the effective zoom

        When we run the second setZoom(2); call, the RenderStyle's zoom value is 2
        already and we'll early return without updating the effective zoom.

        This change moves the updating of the effective zoom in setZoom() to take place
        before the early return due to overwriting with the same value.

        Note: the fact that we're apply the zoom property twice is an inefficiency that
        we should figure out a way to avoid in the future.

        https://bugs.webkit.org/show_bug.cgi?id=134303

        Reviewed by Mihnea Ovidenie.

        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.

        For now, we should disallow accessing local storage after calling window.close() regardless of

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

        Patch by Radu Stavila <stavila@adobe.com> on 2014-07-24
        Reviewed by David Hyatt.

        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.

        REGRESSION(r164401): Placing a caret doesn't bring up autocorrection panel
        https://bugs.webkit.org/show_bug.cgi?id=135278

        Reviewed by Tim Horton.

        The bug was caused by editorUIUpdateTimerFired calling respondToChangedSelection only if the selection was
        triggered by dictation instead of only if it was NOT triggered by dictation.

        Prior to r164401, AlternativeTextController::respondToMarkerAtEndOfWord exited early when SetSelectionOptions
        had DictationTriggered set. r164401 intended to move this check to editorUIUpdateTimerFired to avoid passing
        options around but the boolean condition was erroneously flipped.

        Fixed the bug by negating the condition in editorUIUpdateTimerFired.

        No new tests for now since autocorrection panel cannot be tested automatically. (We should really automate this!)

        we explicitly set a cookie storage, cookie accept policy, and SSL properties based on the
        corresponding values in the old CFURLRequest object (if we have one). This ultimately leads
        to CFNetwork associating the cookies for the request with a different cookie store when we
        handle the request in the NetworkProcess. Instead, we shouldn't set these properties

        Sharing SharedBuffer between WebCore and ImageIO is racy and crash prone
        https://bugs.webkit.org/show_bug.cgi?id=135069
        <rdar://problem/17470655>

        Reviewed by Simon Fraser.

        When passing image data to ImageIO for decoding, we pass an NSData subclass that is a wraper
        around SharedBuffer. This can be a problem when ImageIO tries to access the data on the CA
        thread. End result is data corruption on large image loads and potential crashes. The fix is
        to have SharedBuffer create a copy of its data if the data has been passed to ImageIO and
        might be accessed concurrently.

        Since Vector is not refcounted, we do this by having a new refcounted object in SharedBuffer
        that contains the buffer and we pass that in our NSData subclass WebCoreSharedBufferData.
        Code that would result in the Vector memory moving e.g. append(), resize(), now checks to
        see if the buffer was shared and if so, will create a new copy of the vector. This ensures
        that the main thread does not end up invalidating the vector memory that we have passed it
        to ImageIO.

        No new tests because no functional changes.

        Even though the CSSRegions spec defines the behaviour of a multicolumn region,

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

        Reviewed by David Hyatt.

        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.

        [Win] Crash after plugin is unloaded.
        https://bugs.webkit.org/show_bug.cgi?id=119044

        Reviewed by Darin Adler.

        We need to invalidate all runtime objects when a plugin view is destroyed, in case the plugin is unloaded,
        and one of these runtime objects accesses the plugin function table upon destruction afterwards, which will cause a crash.
        If we use the weak pointer to the runtime object when invalidating, it will be null if it's in the WeakImpl::Dead state.
        This means the runtime object will not be invalidated, possibly causing a crash if the plugin is unloaded.
        It should be safe to use the raw pointer to the runtime object when invalidating, since finalized runtime objects
        will be removed from the set of runtime objects in the method RootObject::finalize().

        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.

        When an accessibility request comes in from the system, we call updateBackingStore() on the

        might delete that accessibility node and its parent, which would cause the node to be deleted.

        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.

        Reduce the chances of a race condition when sharing SharedBuffer
        https://bugs.webkit.org/show_bug.cgi?id=135060
        <rdar://problem/17729444>

        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.

        No new tests because no functional changes.

        Put AVPlayerLayer in a container layer so moving it between inline and fullscreen
        is as easy as adding and removing it from a containter layer; no need to do a layout.

        Make sure fullscreen layers are transparent before moving moving the AVPlayerLayer
        between inline and fullscreen so you don't briefly see the empty fullscreen layers.
