Implement blend modes with UI-side compositing.

PlatformCALayer::setBlendMode() becomes pure virtual, and overridden in
PlatformCALayerMac and PlatformCALayerRemote.

REGRESSION(r164205): WebKit crash @StructureIDTable::get.
<https://webkit.org/b/130539>

Reviewed by Geoffrey Garen.

prepareOSREntry() prepares for OSR entry by first copying the local var
values from the baseline frame to a scartch buffer, which is then used
to fill in the locals in their new position in the DFG frame.  Unfortunately,
prepareOSREntry() was using the DFG frame's frameRegisterCount as the frame
size of the baseline frame.  As a result, some values of locals in the
baseline frame were not saved off, and the DFG frame may get initialized
with random content that happened to be in the uninitialized (and possibly
unallocated) portions of the scratch buffer.

The fix is to use OSREntryData::m_expectedValues.numberOfLocals() as the
number of locals in the baseline frame that we want to copy to the scratch
buffer.

Note: osrEntryThunkGenerator() is expecting the DFG frameRegisterCount
at offset 0 in the scratch buffer.  So, we continue to write that value
there, not the baseline frame size.

Source/WebCore:
RenderLayerBacking::updateGraphicsLayerGeometry() tested whether a
GraphicsLayer had a contents layer to determine whether to call code
that updates the contents rect. However, on Mac, we don't make a contents

Move DOM throttling out of the page throttler

No new tests since it's not web exposed.

DOM timer throttling is currently part of the page throttler which uses per process
state and per page state to determine when to throttle.  This led us to being overly
conservative when turning DOM throttling off.  It should only respond to view state changes.

Additionally since creating extra page throttlers SVG images caused bugs
in tracking state we'll reserve the page throttler for WebKit2 views.  To avoid regressing

https://bugs.webkit.org/show_bug.cgi?id=131838
<rdar://problem/16428630&15705876>

Reviewed by Dean Jackson.

Source/WebCore:
r155977 added logic to adjust the contentsScale of compositing layers
based on a root-relative transform. However, this resulted in
the contentsScale continually changing on layers whose transforms
are changed dynamically, which caused lots of expensive painting.

Fix by bucketing the part of the scale computed from the root-relative transform
into buckets of 0.25 via rounding.

[CSSRegions] Incorrect background paint on positioned element hover
https://bugs.webkit.org/show_bug.cgi?id=131617

Reviewed by Andrei Bucur.

Source/WebCore:
When computing the repaint rect for absolute elements flowed into regions, the Y location of the
region within the flow thread must no longer be added to the repaint rect's location because absolute
positioned elements get pushed down through the regions by their absolute top. So adding the region's
position in the flow thread and then adding the element's absolute top would cause us to add
something twice.

[New Multicolumn] Pagination mode messed up with non-inline axis and reversed direction.
https://bugs.webkit.org/show_bug.cgi?id=131811

Reviewed by Dean Jackson.

Source/WebCore:
Added fast/multicol/newmulticol/compare-with-old-impl/BottomToTop-tb.html

With block axis pagination mode, it is possible to set a column height that is not the same
as the available fill height for a block. The new multi-column code had the assumption that
the column height was the same as the amount of fill room you had available. This is not
the case.

To correct the issue, I added a member variable to RenderMultiColumnSet that stores the
available column height as a separate variable from the computed column height. This allows
the pagination API to specify a different column height that is not the same as the view's
content height.

Even though it isn't involved in the solution, I also patched pageOrViewLogicalHeight on
RenderView to work with the new column code as well.

Source/WebCore:
Patch by Huang Dongsung <luxtella@company100.net> on 2014-04-16
Reviewed by Simon Fraser.

When an element has multiple animations that have different timingFunctions,
the progress of each animation should be calculated using its respective
timingFunction. But at this point, the timingFunction of the first animation is
only used in RenderLayerBacking::startAnimation(), regardless of how many
animations the element has.

getAnimationFromStyleByName() was introduced in r89462 so that the
timingFunction of the correct animation searched by its name would be
used. This patch moves the function to KeyframeValue::timingFunction()
so that RenderLayerBacking reuses this method.

InlineCallFrameSet should be refcounted
https://bugs.webkit.org/show_bug.cgi?id=131829

Reviewed by Geoffrey Garen.

And DFG::Plan should hold a ref to it. Previously it was owned by Graph until it
became owned by JITCode. Except that if we're "failing" to compile, JITCode may die.
Even as it dies, the GC may still want to scan the DFG::Plan, which leads to scanning
the DesiredWriteBarriers, which leads to scanning the InlineCallFrameSet.

So, just make the darn thing refcounted.
