* Add initial support for css-text-3 whitespace handling (#29828)Atbrakhi2023-07-201-153/+195
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add initial support for css-text-3 whitespace handling This adds initial support for whitespace handling from the CSS specification for Layout 2020. In general, the basics are covered. Since test output is very sensitive to whitespace handling, this change incorporates several fixes: 1. Whitespace is collapsed according to the Phase 1 rules of the specification, though language-specific unbreaking rules are not handled properly yet. 2. Whitespace is mostly trimmed and positioned according to the Phase 2 rules, but full support for removing whitespace at the end of lines is pending on a temporary data structure to hold lines under construction. 3. Completely empty box fragments left over immediately after line breaks are now trimmed from the fragment tree. 4. This change tries to detect when an inline formatting context collapses through. Fixes #29994.

* Remove rayon_croissant and clean up `contains_floats` (#29960)Martin Robinson2023-07-191-80/+39
| | | | | | | | | | | Remove rayon_croissant and refactor the way that information about floats in flows bubbles up. This simplifies the code a good deal and lets us take advantage of some more optimized functions provided by rayon. This removes 2 crates from the dependency tree. In addition, this allows avoiding passing `contains_floats` up from every box tree construction function. This makes things simpler, but also opens up the possibility of passing more of these flags up in the future (such as `contains_counters`).

* Detect body elements during layoutMartin Robinson2023-05-041-5/+4
| | | | | | | | | | | | | | | | | During layout it is often useful, for various specification reasons, to know if an element is the `<body>` element of an `<html>` element root. There are a couple places where a brittle heuristic is used to detect `<body>` elements. This information is going to be even more important to properly handle `<html>` elements that inherit their overflow property from their `<body>` children. Implementing this properly requires updating the DOM wrapper interface. This check does reach up to the parent of thread-safe nodes, but this is essentially the same kind of operation that `parent_style()` does, so is ostensibly safe. This change should not change any behavior and is just a preparation step for properly handle `<body>` overflow.

These values are almost always used to size and position a fragment within its containing block, so using the mode of the containing block seems more correct. Note that the `writing-mode` and `direction` properties are disabled in Servo at the moment, so this PR by itself should have no effect: the writing mode of an element is always the same of that of its containing block since they’re both horizontal rtl.
