Before this change AddClipRect was a "special" because it didn't respect scroll frame offset and was meant to be recorded using viewport-relative coordinates. The motivation behind this was to record a "final" clip rectangle computed by intersecting all clip rectangles used by a clip frame. The disadvantage of this approach is that it blocks us from implementing an optimisation to reuse display list if the only change is in the scroll offset, because any scroll offset change leads to invalidating all AddClipRect items within a list. This change aligns AddClipRect with the rest of display list items by making it account for scroll frame offset. It required discontinuing the recording of the intersection of all clip rectangles within a clip frame and instead producing an AddClipRect for each of them. A nice side effect is the removal of code that shifts clip rectangle by `enclosing_scroll_offset()` in a bunch of places, because now it happens automatically in `DisplayList::apply_scroll_offsets()`. |

Ladybird
Ladybird is a truly independent web browser, using a novel engine based on web standards.
Important
Ladybird is in a pre-alpha state, and only suitable for use by developers
Features
We aim to build a complete, usable browser for the modern web.
Ladybird uses a multi-process architecture with a main UI process, several WebContent renderer processes, an ImageDecoder process, and a RequestServer process.
Image decoding and network connections are done out of process to be more robust against malicious content. Each tab has its own renderer process, which is sandboxed from the rest of the system.
At the moment, many core library support components are inherited from SerenityOS:
- LibWeb: Web rendering engine
- LibJS: JavaScript engine
- LibWasm: WebAssembly implementation
- LibCrypto/LibTLS: Cryptography primitives and Transport Layer Security
- LibHTTP: HTTP/1.1 client
- LibGfx: 2D Graphics Library, Image Decoding and Rendering
- LibArchive: Archive file format support
- LibUnicode: Unicode and locale support
- LibAudio, LibMedia: Audio and video playback
- LibCore: Event loop, OS abstraction layer
- LibIPC: Inter-process communication
How do I build and run this?
See build instructions for information on how to build Ladybird.
Ladybird runs on Linux, macOS, Windows (with WSL2), and many other *Nixes.
How do I read the documentation?
