The <fill-rule> in the polygon() syntax is not handled because it doesn't
matter to shape-outside at all.
The reftests are numbered from 018 to avoid conflict with the w3c upstream
ones according to this list.
https://test.csswg.org/harness/results/css-shapes-1_dev/grouped/
Reftest 018 to 025 are under various writing-modes, 026 to 029 are testing
empty float area, 030 to 031 are testing polygon containing horizontal
lines.

Remove WritingMode parameter from LineRight() and LineLeft() in both
FloatInfo and ShapeInfo.
Bug 1316549 Part 3 added the parameter to compute the border radii under
writing-modes correctly. However, bug 1326407 Part 6 later made us cache
border radii, so the WritingMode parameter is no longer needed.

The radii has been cached in the BoxShapeInfo in the previous part. Hence
the rename.
This class will be used to implement inset() in the next part, so the rect
stored isn't necessarily the rect of the <shape-box>. It could be the inset
rectangle. Therefore I rename mShapeBoxRect to mRect to avoid any confusion.

The life cycle of nsFloatManager managed by mNew is same as
nsAutoFloatManager, which lives only in nsBlockFrame::Reflow(). Therefore,
other nsFloatManager pointers are all non-owning ref to the

The difference between CircleShapeInfo's constructor and EllipseShapeInfo's
is the computation of the radii. Therefore, this patch creates a factory
function to distinguish that, so shape-outside: circle() could be
implemented by using EllipseShapeInfo.

Instead of manually adding (aLineLeft, aBlockStart) when creating a shape,
add Translate() to let the shapes implement their only way to move their
origin. FloatInfo could then move the shapes after they're created.

be overridden.
The flow area defined by a shape needs to be clipped to the margin-box per

Create ShapeInfo as a base class for implementing all the shapes. In this
design, we only need to create the correct subclass in FloatInfo's
constructor whenever shape-outside is used rather than manually branching on
StyleShapeSourceType and StyleBasicShape in all the methods like
LineRight(), LineLeft(), etc.
The concrete subclass of ShapeInfo could focus on implementing how its shape
influence the flow area by overriding the needed methods in ShapeInfo.
Move ComputeEllipseLineInterceptDiff() and XInterceptAtY() under the scope
of ShapeInfo so that they could be used by BoxShapeInfo and all the other
ShpapeInfo subclasses yet to come.

Use move constructor for two reasons. 1) The copy constructor is needed only
when appending FloatInfo to mFloats, so using move constructor will likely
be more efficient if some of the member variables support move constructor.
2) Part 6 will added a UniquePtr member to FloatInfo, so using move
constructor becomes necessary.
Also change the return value of AddFloat() to void to simplify the code,
since all the other callers do not check the return value, and
BlockReflowInput::FloatAndPlaceFloat() only asserts in debug mode. I assume
it's safe to omit the OOM check.
