Conrad Irwin fa077a92f8 ui: Add configurable scrollbar reveal behavior (#62282)
Auto-hiding scrollbars currently reveal whenever their prepaint geometry
changes. That matches browser behavior, but it causes continuously
updating views to restart the visibility timer on every content change
even when the user has not scrolled.

Add a per-instance `ScrollbarRevealPolicy`. The default
`ScrollOrContentChange` policy preserves the existing behavior for all
current callers. Views with continuously growing content can opt into
`ScrollOnly`, which reveals only when the offset changes independently
of content size, including when a view remains anchored to the bottom.

Tests pin the default behavior, the opt-in behavior, ordinary scrolling,
stationary content growth, bottom-anchored growth, and scrolling while
content is growing.

Licensing

Zed source code is licensed primarily under GPL-3.0-or-later, with Apache-2.0 components where marked.

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
