* Clean up and document the `send_display_list` interfaceMartin Robinson2023-05-241-16/+11
| | | | | | This moves more members to the CompositorDisplayListInfo struct, which now holds all miscellaneous, non-WebRender data when sending display lists. It also documents what each things sent with a display list does.

| * Further changes required by ServoOriol Brufau2023-05-161-2/+2
| |
* | Start the transition to workspace dependenciesMartin Robinson2023-05-171-19/+19
|/ | | | | | | This will ultimately make it simpler to update crate dependencies and reduce duplicate when specifying requirements. Generally, this change does not touch dependencies that are only used by a single crate. We could consider moving them to workspace dependencies in the future.
* Combine DOM-related concepts in Layout 2020 into dom.rsMartin Robinson2023-05-134-25/+3
|
* Simplify our setup for font metric queries from styleOriol Brufau2023-05-112-3/+2
| | | | | | | | This is a backport of https://phabricator.services.mozilla.com/D157589, by Emilio Cobos Álvarez, plus some additions so that Servo compiles, and some parts from https://phabricator.services.mozilla.com/D144455. Should have no change in behavior.
* Eliminate duplicate Layout DOM wrappersMartin Robinson2023-05-051-2/+6
| | | | | | | | | | There are duplicate sets of Layout DOM wrappers: one for Layout 2013 and one for Layout 2020. As part of cleaning up and simplifying the wrappers, this change parameterizes them on the specific layout data they contain. This allows them to be shared again. In addition, various small cleanups are included. Fixes #29691.
* Detect body elements during layoutMartin Robinson2023-05-043-18/+42
| | | | | | | | | | | | | | | | | 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.
* Clean up debug optionsMartin Robinson2023-05-014-8/+8
|
* Round text decoration thickness to >= 1 device pixelsOriol Brufau2023-04-271-3/+15
| | | | | | | | | | | | | | | | | | Previously the thickness coming from font metrics could be something like 0.7px, so with 1dppx it would be painted as either 1 or 0 device pixels. Enforcing at least 1 device pixel ensures that the decoration will be visible, and rounding to an integral amount of device pixels ensures that the thickness won't vary depending on the position. The specification requires this behavior when text-decoration-thickness is set to a length or percentage. It's not clear if it should also happen by default, but this seems to match other browsers (except for WebKit rounding up instead of to the nearest integer). The test text-decoration-thickness-from-zero-sized-font.html is now failing because of #29675.
* Add support for <iframe> elements for Layout 2020Martin Robinson2023-04-041-9/+8
| | | | | | This change adds support for the <iframe> element to Layout 2020. In addition, certain aspects of the implementation are made the same between both layout systems.
* Move hit testing information out of WebRenderMartin Robinson2023-03-153-12/+17
| | | | | | | | | Store hit testing information in a data structure that sits alongside the display list in the compositor. This will allow the compositor to store more information per-node. The data structure also takes care of de-duplicating information between successive display list entries. In the future, the data structure can be even more aggressive in producing smaller side hit testing lists, if necessary.
* Move more code into ClipScrollState during WebRender DL buildingMartin Robinson2023-03-101-74/+99
| | | | | | | | This change moves a bit more code into the `ClipScrollState` helper during WR display list building as well as inlines build_common_item_properties. This is all in preparation of modifications to this code which will build a Compositor-side scroll tree. It should not change any behavior.
* Bump euclid to 0.22Martin Robinson2023-01-266-29/+47
| | | | | | | | | | | | | - Also updates raqote to latest with an upgrade of font-kit to 0.11 applied on as a patch - Update lyon_geom to the latest version Major change: - All matrices are now stored in row major order. This means that parameters to rotation functions no longer should be negated. - `post_...()` functions are now named `then()`. `pre_transform()` is removed, so `then()` is used and the order of operations changed.
