and remove a bunch of dead code.

5a5460c54e Fix clipping of content outside the bounds of the window.
https://codereview.chromium.org/899753003 incorrectly passed down the
RenderView's clipping rect all the down through transforms instead of
using the one from the LayerPaintingInfo, which is adjusted for transforms
as you recurse down the tree.

0be786f62c Simplify and reduce calls to beginTransparencyLayers.
-Consolidate the beginTransparencyLayers calls. The call
on layer()->parent() was just not needed as best I can tell
and the filter one could just be shared with the non-filter
codepath. FWIW, blink has already made a similar set of changes.
-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.
-Remove unused TransparencyClipBoxMode argument.
-Inline the paintingExtent method.
-Removed unused REVEAL_TRANSPARENCY_LAYERS #define.

c885cea0f7 Cleanup transform-related methods in RenderLayer.
-Get rid of paintsWithTransform.
-Remove currentTransform. It was only ever called with
IncludeTransformOrigin and on non-null transforms.
-Remove renderableTransform. It was only called on
non-null transforms.
-Remove a layer()->parent() branch. The ASSERT had been
added in a previous patch, but the branch wasn't removed.
-Inline makeMatrixRenderable. It was only called in one
place.
-Add a test to make sure that transform origin is corrrectly
excluded from the transform computedStyle.

920920310e Delete RenderLayerModelObject.
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.

c93e7093c1 Never layer-ize RenderInlines.
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.

a267c39c01 Remove the concept of staticly positioned absolutes.
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.

788bb15b3b Address TODOs in the new layer painting and hit testing.
-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.

74290d5007 Move hit testing out of RenderLayer into RenderBox.
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.

e0c039e035 Get rid of HitTestChildBlockBackground walk.
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.

6ee8440f27 Walk render tree instead of render layers for paint.
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.

This is just a mechanical removal. No logic changes
beyond removing the PaintPhaseSelection checks.
Most of these are just early returns to avoid doing

But now that we paint selections during the foreground

we're going to paint everything anyways.

These appear to have been for ensuring that you

Commit efc3afd428bd85fd3d12e0dc941b5eb7248ca30b broke it because
we'd computed an empty foreground layer. Now that background
painting is part of the foreground phase, we need to use the
background rect for clipping. As best I can tell, the
background rect is always >= the size of the foreground
rect, so it should be safe to use.
