This effectively makes ClearFloat() act like it always has
DONT_CLEAR_PUSHED_FLOATS. Thus, the flag is no longer needed.
We need to add an early return condition when the block cannot fit in
ReflowBlockFrame(). Because we now don't return nscoord_MAX when floats
are pushed or split, the `availSpace.BSize(wm)` might equal to zero
rather than negative in this case. It's needed by
testing/web-platform/tests/css/CSS2/floats-clear/floats-clear-multicol-003.html
and layout/reftests/pagination/float-clear-003-print.html

All the callers in nsBlockFrame call BlockReflowInput::ClearFloats(), I
don't feel we need to pass the DONT_CLEAR_PUSHED_FLOATS down to
nsFloatManager. Besides, I'll remove the flag in a later patch.

We always define it to the same thing, and we're inconsistent in whether
we use `CPP_THROW_NEW` or `throw()`, so we might as well just use the
standard C++ thing and get rid of some baggage.

This enables destructors for tagged unions in cbindgen, implemented in:
* https://github.com/eqrion/cbindgen/pull/333
Which allow us to properly generate a destructor for the cbindgen-generated
StyleBasicShape (which now contains an OwnedSlice).
For now, we still use the glue code to go from Box<BasicShape> to
UniquePtr<BasicShape>. But that will change in the future when we generate even
more stuff and remove all the glue.
I could add support for copy-constructor generation to cbindgen for tagged
enums, but I'm not sure if it'll end up being needed, and copy-constructing
unions in C++ is always very tricky.

Per the discussion in:
https://groups.google.com/d/msg/mozilla.dev.platform/P79pwa9z5m8/iPYPAWPHCAAJ
They should be CamelCase, and that's what most of them already do. This converts
the rest, which are a few.
For the ones that already used `e` or `k` prefixes, I've mostly done:
for file in $(rg Type::e layout | cut -d : -f 1 | sort | uniq); do sed -i 's#Type::e#Type::#g' $file; done
For the ones that used uppercase, I've removed the prefix if it was already in
the type name, and turn them into CamelCase.

This patch changes remaining things under `layout/`. However, there are some

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

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.

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

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.

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.

circle() allows the user to define an empty flow area, so IsEmpty() needs to
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.
