 230
 231         The primary issue was that positioningAreaSize was including the top content inset
 232         height, and should not have been, but there were also issues with the "fixedBackgroundPaintsInLocalCoordinates"
 233         code path, which kicks in when the root background is fixed.

 440
 441         Linking this in the normal way should slightly speed up the web process
 442         startup time. We don't need to soft link it: It's present in the
 443         OS X base system and there is no reference cycle with WebKit.
 444
 445         * Configurations/WebCore.xcconfig: Added PrivateFrameworks to
 446         FRAMEWORK_SEARCH_PATHS for Mac and added DataDetectorsCore to
 447         OTHER_LDFLAGS_PLATFORM for Mac. We may want to do this later for iOS too.

 458         DataDetectorsSPI.h header.
 459
 460         * platform/spi/cocoa/DataDetectorsCoreSPI.h: Added. This is the low level
 461         DataDetectorsCore framework, which has no reference cycle with WebKit, and
 462         which we can link to normally. Moved the content here from DataDetectorsSPI.h,
 463         added a USE(APPLE_INTERNAL_SDK) path that uses the system headers, and fixed
 464         the incorrect return type on DDScannerScanQuery, which was detected when
 465         using the system headers in conjunction with this file.
 466
 467         * platform/spi/mac/DataDetectorsSPI.h: Removed the content of this file that
 468         was actually about DataDetectorsCore. Also added a USE(APPLE_INTERNAL_SDK)
 469         path that uses the system headers and moved a few stray DataDetectors SPI
 470         definitions from elsewhere into this header.

1065         After r183300 we can detached layer backing store when outside the coverage region.
1066         However, position:fixed layers are moved around by the ScrollingCoordinator behind
1067         GraphicsLayer's back, so we can do layer flushes with stale information about layer
1068         geometry.
1069
1070         To avoid dropping backing store for layers in this situation, prevent backing
1071         store detachment on layers registered with the ScrollingCoordinator as viewport-constrained
1072         layers. Preventing detachment on a layer also prevents detachment on all descendant

1176         Applying a filter on an SVG element, which is larger than 4096 pixels, causes this element to be rendered shifted to the left
1177         https://bugs.webkit.org/show_bug.cgi?id=144335
1178
1179         Reviewed by Darin Adler.
1180
1181         When the SVG element is larger than 4096x4096 pixels and it has a filter,
1182         a clipper or a masker, the ImageBuffer which is created for drawing the
1183         sourceGraphicBuffer has to be clamped to this size. The reason for this
1184         clamping is the FilterEffect simply ignores processing any ImageBuffer
1185         larger than this size.
1186
1187         The bug was happening because we did not propagate the clamping logic to
1188         the FilterEffect. The FilterEffect result ImageBuffer was not clamped as
1189         what we do for drawing the sourceGraphicBuffer. If only the destination
1190         point is specified, the GraphicsContext::drawImageBuffer() assumes the
1191         source and the destination images have the same size which is not true
1192         with the clamping.
1193
1194         The fix is to add the clamping logic to the FilterEffect. Two places we
1195         need to change. (1) FilterEffect::createImageBufferResult() has to apply
1196         the same clamping we do in SVGRenderingContext::createImageBuffer(). (2)
1197         FilterEffect::drawingRegionOfInputImage() has to consider the clamping
1198         when mapping from absolute coordinates to the ImageBuffer coordinates.

1424
1425         Reviewed by Dean Jackson.
1426
1427         In WebKit1 on Mac, we allowed iframes to be composited independently of their
1428         parent document, relying on the fact that the frame's platform view can host
1429         a layer-backed view. However, this ran into bugs (rdar://problem/18862298),
1430         and triggers the assertion at the end of FrameView::updateLayoutAndStyleIfNeededRecursive(),
1431         because the compositing update after a layout can dirty style in notifyIFramesOfCompositingChange().
1432
1433         Removing the WK1-only code path solves these problems. It also eliminates the need

1654
1655         Reviewed by Simon Fraser.
1656
1657         The calculation of scroll snap points was incorrect because it did not account for margins or padding.
1658         This was fixed by using the "paddingBoxRect" to represent the overall size of the view area, and
1659         subtracting the relevant padding when computing the size of the scroll snap offsets.
1660
1661         Extend testing internals with accessor methods to retrieve string representations of the scroll snap
1662         offsets and scroll snap coordinates computed during layout. These values are used in the new
1663         'css3/scroll-snap/scroll-snap-offsets-and-coordinates.html' test.

2403         This patch ensures that we don't emit empty text for the text iterator.
2404         In TextIterator::handleTextNode before emitting a string, certain characters (\n \t) need to
2405         be replaced with space. When such character is found, we emit the string we've processed so far and
2406         handle the replacement during the next callback.
2407         When the first character in the string needs replacing, there's nothing to emit. However if we don't
2408         handle at least one character, TextIterator::advance believes that processing is done and never calls
2409         TextIterator::handleTextNode back with the rest of the string.

2689         [ATK] AX: figure out platform difference for ATK to make accessibility/table-cell-display-block.html work
2690         https://bugs.webkit.org/show_bug.cgi?id=143083
2691
2692         Reviewed by Chris Fleizach.
2693
2694         The main platform difference was that ATK was mapping the td element to
2695         the accessible table cell, and the render block resulting from the style
2696         wound up being the cell parent. In contrast, AX API was mapping the cell
2697         element to an AXGroup which was a child of the AXCell. Rather than try to
2698         bend yet another case to the will of our individual platforms' table needs,
2699         it made more sense to clean up the code that is competing and move toward
2700         more platform-unified handling. This is the first step in that direction,
2701         with ATK moving closer toward the WebCore/AX API mapping.
2702
2703         No new tests. Instead, modified and fixed the test which was being skipped
2704         for GTK, and also updated the expectations of some Mac tests whose FIXMEs
2705         should now be fixed.

2899         FrameView::updateLayoutAndStyleIfNeededRecursive() only forces layout on rendered
2900         frames, by virtue of using its Widget children which are FrameViews.
2901
2902         However, FrameView::flushCompositingStateIncludingSubframes() iterated over
2903         all frames, and return false if any subframe needed layout. Thus, if it saw
2904         non-rendered frames (which are never laid out), it would return false,
2905         which causes the CFRunLoopObserver that drives flushing to run again.

3006         This patch introduces a new mechanism to apply and remove text decorations. This is necessary because text
3007         decorations are always additive and we can't differentiate whether we're adding or removing a text decoration.
3008         Conceptually, we need four values for text decorations: adding underline, removing underline, adding
3009         line-through, and removing line-through but we have only three: underline, line-through, none.
3010
3011         After this patch, there are three mechanism by which text decorations states are kept tracked. While applying
3012         or removing text decorations, we use newly added m_underlineChange and m_strikeThroughChange in EditingStyle.
3013         For the typing style, we use -webkit-text-decorations-in-effect to store the state since we need to preserve
3014         every type of text decorations such as overline in addition to underline and line-through. Once applied, all
3015         text decorations should be expressed in terms of the standard text-decoration property.

3111         REGRESSION (r178156): CSS Parser incorrectly rejects valid calc() in padding-right property
3112         https://bugs.webkit.org/show_bug.cgi?id=144584
3113         <rdar://problem/20796829>
3114
3115         Reviewed by Darin Adler.
3116
3117         The CSS parser was rejecting calculated values at parsing time if it
3118         considered the value was negative and the CSS property did not allow
3119         negative values. However, doing so at this point will not always work
3120         because we don't necessarily know the font-size yet (for e.g. for
3121         calc(0.5em - 2px). Also, rejecting negative calculated values is not
3122         the right behavior as the the specification. The specification says
3123         we should clamp:
3124         http://dev.w3.org/csswg/css-values-3/#calc-range
3125
3126         This patch updates validateCalculationUnit() to stop marking the value
3127         as invalid if it is negative. Instead, let the CSSCalcValue's permitted
3128         range clamp the value as needed.
3129
3130         This bug was causing the bottom graphic on aldentrio.com to not be
3131         rendered properly.

3173         [CSS Box Alignment] Upgrade justify-content parsing to CSS3 Box Alignment spec.
3174         https://bugs.webkit.org/show_bug.cgi?id=144442
3175
3176         Reviewed by David Hyatt.
3177
3178         Upgrade the justify-content property to the last CSS3 Box
3179         Alignment specification. It defines a different enumeration for
3180         Positional and Distribution alignment, which requires changes in
3181         the FlexibleBox implementation.
3182
3183         A new parsing function has been implemented to replace the basic
3184         keyword IDs validation. Because of the complexity of the new
3185         values, a new CSSPrimitiveValue derived class has been defined
3186         which simplifies considerably the parsing logic.
3187
3188         We will follow the same approach than for Self Alignment, defining
3189         a single class to hold all the related alignment data. This makes
3190         possible to use a StyleBuilderConverter function instead of custom
3191         builder functions for these properties.

3372         Change PassRefPtr in create() factory functions with Ref. In some functions,
3373         it returns RefPtr when it might have a chance to return nullptr.
3374
3375         No new tests, no behavior changes.
