65059b8539 servo: Merge #7150 - layout: Take relative position offsets for inlines and inline-blocks into account only once (from pcwalton:position-relative-inline-block); r=mbrubeck
There were two bugs here: (1) relative position applied to
scanned/unscanned text fragments independently of the container element
that applied that relative position, causing double-counting; (2)
relative position applied to inline block fragments independently of the
wrapped block itself, causing double-counting.

Closes #7067.

05e3c47b79 servo: Merge #7024 - layout: Rewrite whitespace stripping (from pcwalton:whitespace-stripping); r=mbrubeck
This patch makes Servo unconditionally strip whitespace before text run
scanning (assuming that the `white-space` property allows it). Whitespace
stripping during reflow is now only used for handling whitespace at the ends of
lines; reflow now never attempts to handle ignorable whitespace.

Many CSS tests pass now. There are some new failures, however.

The following reference tests now fail due to a pre-existing bug whereby
whitespace is used to calculate the position of inline hypothetical boxes for
elements with `display: inline; position: absolute`:

* `absolute-replaced-height-036.htm`
* `vertical-align-sub-001.htm`
* `vertical-align-super-001.htm`

The following reference tests fail due to a pre-existing bug whereby we don't
handle `font-size: 0` properly in inline reflow:

* `font-size-zero-1.htm`
* `font-size-zero-2.htm`

The following reference test fails due to the fact that it relied on our
incorrect insertion of whitespace to make room for the black background:

* `inline-formatting-context-007.htm`

The failing `float-applies-to-*` CSS 2.1 tests never really should have

2b915bbedc servo: Merge #6289 - Make LOCAL_CONTEXT_KEY safe and non-leaky (from nnethercote:unleak-LOCAL_CONTEXT_KEY); r=pcwalton
`LOCAL_CONTEXT_KEY` is currently a `Cell<*mut LocalLayoutContext>`. The use
of the raw pointer means that the `LocalLayoutContext` is not dropped when
the thread dies; this leaks FreeType instances and probably other
things. There are also some unsafe getter functions in `LayoutContext`
(`font_context`, `applicable_declarations_cache` and
`style_sharing_candidate_cache`) that @eddyb says involve undefined
behaviour.

This changeset changes `LOCAL_CONTEXT_KEY` to
`RefCell<Option<Rc<LocalLayoutContext>>>`. This fixes the leak and also
results in safe getters.

(Fixes #6282.)

* Simpler image cache API for clients to use.
 * Significantly fewer threads.
   * One thread for image cache task (multiplexes commands, decoder threads and async resource requests).
   * 4 threads for decoder worker tasks.
 * Removed ReflowEvent hacks in script and layout tasks.
   * Image elements pass a Trusted<T> to image cache, which is used to dirty nodes via script task. Previous use of Untrusted addresses was unsafe.
   * Image requests such as background-image on layout / paint threads trigger repaint only rather than full reflow.
 * Add reflow batching for when multiple images load quickly.
   * Reduces the number of paints loading wikipedia from ~95 to ~35.
 * Reasonably simple to add proper prefetch support in a follow up PR.
 * Async loaded images always construct Image fragments now, instead of generic.
   * Image fragments support the image not being present.
 * Simpler implementation of synchronous image loading for reftests.
 * Removed image holder.
 * image.onload support.
 * image NaturalWidth and NaturalHeight support.
 * Updated WPT expectations.

Only simple alphabetic and numeric counter styles are supported. (This

Although this PR adds a sequential pass to layout, I verified that on

the time spent in the parallelizable parts of layout. So I don't expect
this to negatively affect our parallelism expect perhaps in pathological

195b198cde servo: Merge #4952 - Dont draw interior borders for text run fragments (from bjwbell:borders-txt-nodes); r=pcwalton
Inline fragments that are part of a text run don't have interior borders.
So don't draw interior borders or include them when calculating positioning.

Fixes https://github.com/servo/servo/issues/4658, where multiple text nodes that are adjacent have distinct borders.

1f9816fcf2 servo: Merge #5064 - Fix setting display:none after a layout where the element was visible (from glennw:hide-after-layout); r=pcwalton
Prior to incremental layout, the code would remove the existing
construction result. However, with incremental layout the construction result
is cloned rather than removed. This change ensures that the previous
construction result is cleared when an element's display type
changes to none.

d668ccc421 servo: Merge #4458 - layout: Implement floated list items (from pcwalton:floated-lists); r=mbrubeck
This patch also makes Servo not crash when
`generated_containing_block_rect()` is called on a list item (as, for
example, GitHub does), and for good measure I added the fix to other
flows as well.
