Previously, clip nodes interned the local clip information, but stored the spatial node and the local position as part of the instance. This was required since the local position of clips would change when a new display was sent after scrolling. However, since we now handle this via external scroll offsets, the local position is stable, and we can intern both the position and spatial node. This greatly simplifies some in-progress work for picture caching, where we want to be able to quickly identify clip chain nodes that are shared between elements of a display list. With this change, comparing the item uid of the interned clip node is enough to guarantee equality of the shared clips.

WebRender
GPU renderer for the Web content, used by Servo.
Note that the canonical home for this code is in gfx/wr folder of the mozilla-central repository at https://hg.mozilla.org/mozilla-central. The Github repository at https://github.com/servo/webrender should be considered a downstream mirror, although it contains additional metadata (such as Github wiki pages) that do not exist in mozilla-central. Pull requests against the Github repository are still being accepted, although once reviewed, they will be landed on mozilla-central first and then mirrored back. If you are familiar with the mozilla-central contribution workflow, filing bugs in Bugzilla and submitting patches there would be preferred.
Update as a Dependency
After updating shaders in WebRender, go to servo and:
- Go to the servo directory and do ./mach update-cargo -p webrender
- Create a pull request to servo
Use WebRender with Servo
To use a local copy of WebRender with servo, go to your servo build directory and:
- Edit Cargo.toml
- Add at the end of the file:
[patch."https://github.com/servo/webrender"]
"webrender" = { path = "<path>/webrender" }
"webrender_api" = { path = "<path>/webrender_api" }
where <path> is the path to your local copy of WebRender.
- Build as normal
Documentation
The Wiki has a few pages describing the internals and conventions of WebRender.
Testing
Tests run using OSMesa to get consistent rendering across platforms.
Still there may be differences depending on font libraries on your system, for example.
See this gist for how to make the text tests useful in Fedora, for example.
