With this gone, cursors will no longer change
on hover when running Sky on a desktop.
Then again the iGeneration doesn't
probably even know what a mouse is, let alone
have a burning desire to set a CSS3 custom-cursor.

We only ever create RenderParagraphs now. The only non-trivial change here
is making RenderView a RenderFlexibleBox. This required changing custom.sky.
That test was written in a fragile way that behaved differently if we
did multiple layouts. Instead, having it be less racy and only change
values during the test itself.
This also throws a wrench in moving all the layout code to dart
because we can't set the layout manager on the RenderView. Maybe
we need to explicitly let you do so.

-Make display:flex, flex-direction: column, flex-shrink: 1 the default.
-Simplify StyleAdjuster::adjustStyleForAlignment to remove special cases we
won't need as we make flex the default and remove absolute positioning.
-Fix a bug this exposed in column flexboxes where we'd apply the wrong edge
of border/padding/margin.
-For now leave the default of align-items:stretch. The main change here is
that iframe/img will do width:auto the same as blocks (i.e. the width of
the parent). I think this is a good change, but we'll have to see how it feels
in practice.

-Temporarily add setting override width as well so that we correctly bypass in RenderBox::computeLogicalWidth.
-Add setNeedsLayout so that the author code can force layouts (e.g. when the container's width changes).
-Have setLayoutManager force a reattach of the element if it's renderer wasn't a custom layout one before.
-Remove the laying out of children from RenderCustomLayout::layout. This is the job of the author code.
-Add a test case.

This allows setting x/y/width/height directly on an element
during a synchronous layout callback. At the moment, you can do
dangerous things (e.g. change tree structure). In a followup patch
we'll make that impossible via an IDL guard.

StockMenu was creating a container for the sole purpose of applying style to
PopupMenu. Now we just use a StyleNode.
Also, I've reverted the change to make box-sizing default to border-box. It
turns out that CL wasn't effective because we didn't use the initialBoxSizing
function to initialize box sizing. I've made us use initialBoxSizing but switch
the default back to content-box because actually using border-box breaks a
bunch of stuff.

This CL adds just enough custom painting to Sky to make
sky/examples/painting/circle.sky draw a circle. Over time, we should be able to
elaborate this system into something interesting and to make it actually work
in a reasonable way.

hit-testing needs to walk in backwards order from paint.
The previous attempt at reverse sorting by z-index didn't
reverse things with the same z-index. Instead, forward
sort the same way as we do with paint and then reverse
the whole vector.

-Remove AbsoluteClipRects. It's never used.
-Inline some static functions. In the process,

In theory, this patch fixes that, but I didn't test it

It doesn't do anything RenderLayer specific anymore. This
does mean adding another pointer to RenderBox. We might want
to do something about that eventually, but for now it seems fine
to make forward progress in terms of getting rid of the RenderLayer
tree.

-Remove RenderLayerFilterInfo. It was just a static map for
FilterEffectRenderers. Instead, put the FilterEffectRenderer
directly on RenderLayer.
-Make FilterEffectRenderer not be RefCounted. This involved
deleting a ton of dead code around ReferenceFilters since they
were the other subclass of Filter. As best I can tell,
reference filters are already don't parse in Sky, so this should
just be removing dead code.

-Consolidate the beginTransparencyLayers calls. The call

and the filter one could just be shared with the non-filter

-Don't walk up the tree calling beginTransparencyLayer.
We're doing this in a recursive call down, so we've already
created the transparency layer for any transparent ancestors.

Merge most of it into RenderBox. Only RenderBoxes can have
layers now. This also meant a bit of code could be cleaned up
since some virtuals (e.g. updateFromStyle) are no longer needed
since they're only called on RenderBoxes.
collectSelfPaintingLayers is the only bit that's moved into
RenderBoxModelObject instead of RenderBox. That's because we
need to be able to recurse down into RenderInlines since they
may contain RenderBoxes that have selfPaintingLayers.

This removes support for opacity, filters and clip-path
on RenderInlines. If you want inline content that uses
these properties you need to use an inline-block. We
may want to add back support for opacity or filters
on inlines eventually, but we'd implement it differently
and right now they're getting in the way.

On the web, if you set position:absolute, but not
top/right/bottom/left, then the absolute goes where it
would have gone if it wasn't positioned. The use-cases for
this are slim and it introduces a lot of complexity to the
engine.
Also changes behavior in the presence of direction:rtl.
On the web, direction:rtl and top/left:auto would
sometimes set right:0. Instead we always position at
0,0 if the opposing values are auto.
This removes the code for this positioning and allows
simplifying a bunch of dirty bit handling code since
we don't need to setNeedsLayout if lines move around
or wrap differently.
The test cases did change their output, but the new
positioning all looks correct to me.

We only need to walk the immediate children of the paragraph.
The other inline children of the paragraph will get paint called
on them and they will then appropriately add the self painting
layers to the array inside their paint calls.

-ASSERT(layer()->parent()) in all the transform codepaths since
the RenderView cannot have a transform.
-Early return if the content rect does not intersect the
damage rect in the painting code. We don't need to do
any of the filter and/or transparency dance if we're
not going to paint anything. This also allowed for
removing the shouldPaintContent bool.
-Remove a random style() null check that can't be hit.

Change hit testing to walk over the render tree instead of
the RenderLayer tree. This is a step in the direction of
removing the RenderLayer tree entirely.
For now, there's a few calls back into RenderLayer that
will be removed in a followup patch. This patch also
breaks hit testing on transformed inlines. I'll be
removing the ability to transform inlines in a
followup patch anyways, so it's ok for hit testing
to give the wrong result temporarily here.
Almost all of this patch is just moving code from
RenderLayer to RenderBox. The primary substantive change
is in RenderBox::hitTestLayer. Instead of having
hitTestChildren calls, we call collectSelfPaintingLayers,
reverse sort by z-index (so we start at the top),
and then iterate over the result.
The test-case also exposes that we don't correctly hit
transformed elements inside inline-blocks. I went back as
far as 4153b8a515d54275934d4244aaf2d5a7a8fe3333 and the
bug still happened.

I'm not 100% what this was for, but looking at Blink,
it appears that HitTestChildBlockBackground being different
from HitTestBlockBackground had something to do with
multi-column/regions, which we don't have. I believe
this patch doesn't change any behavior.
Also added to the elementFromPoint test in order to
get more test coverage of the hitTesting code.

This is the first step of getting rid of RenderLayer.
Instead of walking the RenderLayer tree, wall the RenderObject
tree and add any layers encountered to a vector to paint later.
This patch just consolidates and move the code from RenderLayer
to RenderBox and then changes the children painting to
iterate over the vector. Therefore we walk the RenderObject tree.
We still call out to RenderLayer in a bunch of places.
A followup patch will get rid of those.
