Reviewed by Rob Buis.

Source/WebCore:

This patch updates the computed position values used for blending to be a horizontal
left offset and a vertical top offset. When positions include a center, bottom, or
right position offset, it is converted to the appropriate top/left coordinate as
a calc expression. Serialized values still use the original bottom/right directions
when present, and also omit the top/left keywords where possible.

Updated parsing and animation tests.

* css/BasicShapeFunctions.cpp:
(WebCore::valueForCenterCoordinate): Use the simplified BasicShapeCenterCoordinate,
which includes an offset and whether the direction is from the top/left or bottom/right.
(WebCore::valueForBasicShape): Ditto.
(WebCore::convertToCenterCoordinate): Ditto.
(WebCore::basicShapeForValue): Ditto.
(WebCore::floatValueForCenterCoordinate): Ditto.
* page/animation/CSSPropertyAnimation.cpp:
(WebCore::blendFunc): Remove the RenderBox parameter, which is no longer needed.
* rendering/style/BasicShapes.cpp:
(WebCore::BasicShapeCenterCoordinate::updateComputedLength): Calculate the computed
position offset for this center coordinate.
(WebCore::BasicShapeRectangle::blend): Remove the RenderBox parameter.
(WebCore::DeprecatedBasicShapeCircle::blend): Ditto.
(WebCore::BasicShapeCircle::blend): Ditto.
(WebCore::DeprecatedBasicShapeEllipse::blend): Ditto.
(WebCore::BasicShapeEllipse::blend): Ditto.
(WebCore::BasicShapePolygon::blend): Ditto.
(WebCore::BasicShapeInsetRectangle::blend): Ditto.
(WebCore::BasicShapeInset::blend): Ditto.
* rendering/style/BasicShapes.h:
(WebCore::BasicShapeCenterCoordinate::BasicShapeCenterCoordinate): Simplify
BasicShapeCenterCoordinate to contain an offset and a direction. Also add a
computed length, which is an offset from the top/left direction.
(WebCore::BasicShapeCenterCoordinate::direction):
(WebCore::BasicShapeCenterCoordinate::computedLength):
(WebCore::BasicShapeCenterCoordinate::blend):

LayoutTests:

Update existing parsing and animation tests. For parsing tests, top / left keywords
are omitted whenever possible. For animation tests, animations to bottom / right
offsets will use calc values based from the top / left direction.

* animations/resources/animation-test-helpers.js:
(parseBasicShape): Parse non-numerical arguments to the shape function.
(basicShapeParametersMatch): Match non-numerical arguments to the shape function.
* fast/shapes/parsing/parsing-shape-inside-expected.txt: Update serialized values
to omit top / left keywords when possible.
* fast/shapes/parsing/parsing-shape-outside-expected.txt: Update serialized values
to omit top / left keywords when possible.
* fast/shapes/parsing/parsing-test-utils.js: Modify shape parsing test expectations.
* fast/shapes/shape-outside-floats/shape-outside-animation-expected.txt: Ditto.
* fast/shapes/shape-outside-floats/shape-outside-animation.html: Ditto.
