Per the css-contain specification, size contained element must be sized as if
they were empty. The code added to handle size containment shortciruits the
(inline) size calculations, and returns 0. However, an empty <select> element
is rendered as if it contained a and some padding gets added to it by
the UA stylesheet (forms.css). This causes reftest that check that
size-contained <select> elements and empty ones look the same.
This commit fixes this by also shortcircuiting the (inline) size calculations
and returning 0 for empty <select> elements.
Replacing the by a zero width space would not have been enough, since
padding would still be added. It would have been possible to add it in the
inline size calculations of size-contained <select> elements as well, but this
padding serves not purpose when the element is empty, so removing it from there
has no downside, and shortcircuitig both cases is simpler (and marginally
faster) than adding the padding in both cases.

Flex containers resolve a main-axis size for each of their flex items, and they
impose this size on the flex items by stomping on the items'
ReflowInput::ComputedISize() or ComputedBSize() data. For cases when we're
stomping on the flex item's block-axis, then this can make us improperly treat
this size as definite (i.e. use it for percent resolution).
The flexbox spec does call out some cases where the item's size *is* supposed
to be considered definite[1], but if we're not in one of those cases, we need
to be careful to treat the size as indefinite even though it's been resolved.
This patch achieves this by:
- adding a flag to FlexItem, which gets set in cases where we know we need to
treat the size as indefinite.
- adding a flag to ReflowInput, which gets set whenever a ComputedBSize is
imposed (if the FlexItem had its flag set).
- adding some code to the ReflowInput percent-resolution codepath to test for
this flag and skip past percent-resolution if it's set.
This patch makes us pass all of the existing testcases in the web-platform-test
"percentage-heights-003.html". This patch also adds a few more subtests
there to exercise cases where the flex container and item have orthogonal
writing-modes.
(Note the XXXdholbert comments in the patch about items being "fully
inflexible" in some cases in order to be treated as having a definite size.
If I were to address that comment here, then we would start failing the
web-platform-test "percentage-heights-005.html", which all browsers currently
pass[2]. Therefore, I'm not adding that restriction at this point.)

In the previous commit, we expanded layout viewport height but during reflow
the expanded layout viewport size hasn't reflected in
ScrollReflowInput::mContentsOverflowAreas.ScrollableOverflow(). We explicitly
need to use the expanded height to tell whether we need vertical vertical
scrollbars or not.
Note that the expanded layout viewport height should NOT be used for non-overlay
scrollbars cases since, for example, if the content width is specified by
`width: 100%`, the non-overlay vertical scrollbar narrows down the content's
used width a little bit because of the vertical scrollbar width, which in turn
the minimum scale gets bigger because the content's width became bit narrower,
thus the layout viewport size calculated with the minimum scale gets smaller,
then it results the vertical scrollbar no longer needs to be rendered, thus
the minimum scale gets back to the original value, then the vertical scroll
needs to be rendered again, thus this sequence of processes happens repreatedly.

In ColumnSetFrame's reflow methods, mCBReflowInput is equal to
mParentReflowInput in most of the cases.
However, a multicol <button> has the HTMLButtonControl as the outermost
frame, where ColumnSetWrapper is its -moz-button-content anonymous
child. In this case, mCBReflowInput is HTMLButtonControl's reflow input.
To get the correct computedBSize of ColumnSetWrapper, we need to use
mParentReflowInput.

This annotation matches the one in

select-disabled-fieldset-1.html (which should really produce the same
rendering, and have the same reference).
This is a one-pixel fuzz on the fieldset border near the bottom right corner.
It's unclear which patch of this pushlog, if any, caused this:
https://hg.mozilla.org/mozilla-central/pushloghtml?changeset=4a49d88894d8d88f87760ac59ae35b2158fab7b2
Probably bug 1404868, which added reftests and tickled something. But it seems
this is not really that patches' fault, so to avoid speculatively backing it
out, with the chance of it not being the offender, let's mark it as fuzzy for
now.
I kept the exact same annotation as the other test, since this goes directly to
central, so it's less risky.
We could try to make it fuzzy-if(Android,9-9,1-1), maybe, though given it seems
to be affected to changes to adjacent reftests that may be unwise.

This patch adds an assertion that documents the invariant that this code

Currently items are painted with a context that has a transform of
-mLayerBounds.TopLeft(). This means that if TopLeft() changes the commands
will be in the wrong place because the -TopLeft() offset is baked into the
recording.
I don't think we've ever needed to support painting without this transformed
baked in so there were some infrastructure changes that needed to be made to
make this possible. Most of the problems come from the use of
gfxContext::GetClipExtents which expose the bounds of the underlying surface.
The biggest of these was fixed by the CreateClippedDrawTarget rewrite. The rest
should be handled by ensuring that the DrawTarget has bounds that are at least
as big as the union of the individual item bounds. i.e. GetClipExtents should
never intersect with bounds of the item.
This change has a couple of parts:
1. Store mLayerBounds.TopLeft() in the recording so that it will be subtracted
during replay
2. Use mLayerBounds as the Rect of the RecordingDrawTarget
3. Don't include mLayerBounds.TopLeft() in the transform during recording.
4. Adjust the dirty rect by recordingOrigin before we use it as a clip so that
it stays in the right place.
5. In PaintContainerItem the bounds parameter of PushLayer is in device space
so we need to account for the shift in the location of device space in the
DrawTargetRecording.

Before this patch, we would use fallback for all border images. Now for
all but vector images we will use the WebRender border images
primitives. Vector images are an exception because the fallback is
clever in that it upscales the vector image and clips to only draw the
region it requires. This avoids artifacting but to do something similar
for WebRender as it is currently defined, we would increase our CPU and
memory footprint as we would need to produce the entire vector image
upscaled, not just the parts we need. In the future we should change

When WebRender is enabled, the test/reference difference is much greater because many of

The arguments for the respective container elements apply to their immediate

Our algorithm for dividing a page up into separate font inflation flow roots
seems mostly based on the idea that a new Block Formatting Context (BFC) should
go hand in hand with a font inflation flow root.
Flex containers so far didn't follow that rule, since they technically create a
new *Flex* Formatting Context (FFC) and possibly also because nobody thought
about font inflation when implementing nsFlexContainerFrame.
This leads to all flex containers being counted against the next higher-level
flow root, meaning that a lot of small flex containers can get inflated if their
sum total of text *collectively* exceeds the font inflation threshold.
This alone is likely undesired most of the time, but is then also aggravated by
the fact that our flexbox behaviour under font inflation is somewhat buggy (bug
1142461).
As apart from the different layout rules inside the container, a FFC behaves
very much like a BFC in that it establishes a new formatting context, flex
containers should therefore correspondingly become font inflation flow roots,
too, and therefore be considered individually for font inflation.
As far as I can tell, with this change we'll also match Blink's behaviour in
that regard.
For completeness's sake, we'll make grid containers follow the same principles,
even though hopefully grids on non mobile-friendly pages should hopefully be
somewhat rarer than flexboxes.

From the CSSOM View spec[1];
The scroll-behavior property of the HTML body element is not propagated to
the viewport.
The reason why this change fixes the test case in this commit is that we don't
have two different scrollable frames for <html> and <body> respectively if we
don't propagate scroll-behavior property from <body> to <html> so that we can
properly find the `flow root` of sticky position elements.
In other words, in the case where both of <html> and <body> have properties
that are propagated from <body> but they are different we have two scrollable
frames as a candidate of the 'flow root' for the sticky position element in
the test case, one is the scrollable frame for <html> and the other is the
scrollable frame for <body>. That means that
nsLayoutUtils::GetNearestScrollableFrame doesn't return what we want in some
places, for example we have a pretty similar issue in case of
overscroll-behavior which is bug 1561107.
Note that the test position-sticky-root-scroller-with-scroll-behavior.html is
almost copy-and-pasted from
/css/css-position/position-sticky-root-scroller.html [2] in wpt, the reason why
we put the test in /css/cssom-view is that there is a handy function to wait
for async scroll completion.

root of each primitive, which can be found by the primitive's
spatial node indices. If a scene contains too many slices, then
picture caching is disabled on the page, to avoid excessive texture
memory usage, and rendering falls back to rasterizing each frame.
The specific changes in this patch are:
* Support tile caches for multiple scroll roots, allowing the
entire page (including fixed divs and the main UI bar) to be
cached in most cases, in addition to the main content.
* Remove requirement to read tiles back from the framebuffer.
Instead, they are drawn into the picture cache target tiles,
and blitted to the screen. This is slightly slower than the
existing picture caching when content is constantly changing,
however this cost will disappear / become irrelevant when
the OS compositor integration work is complete.
* Switch picture cache render targets to be nearest sampled (they
are always rendered 1:1) and support depth buffer targets.
* Make use of the external scroll offset support to allow removal
of the primitive correlation hacks in the previous picture
caching implementation. Also allows storing of primitive
dependencies in picture space rather than world space, which
reduces floating point inaccuracies.
* Determine if each tile and picture cache can be considered
opaque. This is used to determine whether subpixel AA text
rendering is available on a slice, and for rendering optimizations
related to disabling blending and/or tile clears.
* Use the clip chain instance results from the recent visibility pass
work to determine clip chain dependencies. This results in fewer
clip item dependencies in tiles, which is faster to check validity
and reduces redundant invalidations.
* Remove extra overhead during batching related to batch lists,
and region iteration, as they are no longer required.
* Support PrimitiveVisibilityMask during batching. This allows a
single traversal of a picture (surface) root during batching to
efficiently construct multiple alpha batcher objects (typically
one per invalida tile).
* Picture caching is now handled implicitly by WR, depending on
the content of the scene. There is no requirement for client
code to manually select which stacking context should be cached.
* Simplify how clip chain / transform dependencies are tracked by
picture cache tiles.
* Support pushing / popping enclosing clip chain roots without
the need for a stacking context / picture in some cases. This
simplifies the logic to split the scene into multiple slices.
The main remaining work in this area is (a) extend the code to
optionally provide each slice as an input to the OS compositor
rather than drawing the tiles in WR, and (b) support multi-resolution
tiles so that we reduce the draw call, batching and render target
overhead in cases where much of the page content is changing.

Note that the geckoview annotation will override the previous Android
annotation, but I verified that on geckoview debug the test seems to
pass so overriding the Android&&debug annotation should be ok.

The fuzziness in the position-dynamic-changes reftests seems nondeterministic.
The fuzziness annotations in the previous patch were what I got after a few
iterations of do-a-try-push-and-update-annotations, but there are still more
failures showing up in subsequent try pushes. I visually checked all the
failures and they are all just fuzzy in different places, but intermittent.
This patch updates the fuzziness annotations on these tests to the maximum
that I encountered on any test, which is (2, 1382).
I'm keeping this as a separate patch because I think it might be valuable
in version control history to have the actual numbers seen on try which
are in the previous patch.

There are a number of failures, for which I've filed separate bugs.
And then a lot of fuzziness. I manually inspected the reftest analyzer
results on try pushes to distinguish failures vs fuzziness.
