Michael SloanandThorsten Ball 527c9097f8 linux: Various X11 scroll improvements (#18484)
Closes  #14089, #14416, #15970, #17230, #18485

Release Notes:

- Fixed some cases where Linux X11 mouse scrolling doesn't work at all
(#14089, ##15970, #17230)
- Fixed handling of switching between Linux X11 devices used for
scrolling (#14416, #18485)

Change details:

Also includes the commit from PR #18317 so I don't have to deal with
merge conflicts.

* Now uses valuator info from slave pointers rather than master. This
hopefully fixes remaining cases where scrolling is fully
broken. https://github.com/zed-industries/zed/issues/14089,
https://github.com/zed-industries/zed/issues/15970,
https://github.com/zed-industries/zed/issues/17230

* Per-device recording of "last scroll position" used to calculate
deltas. This meant that swithing scroll devices would cause a sudden
jump of scroll position, often to the beginning or end of the
file (https://github.com/zed-industries/zed/issues/14416).

* Re-queries device metadata when devices change, so that newly
plugged in devices will work, and re-use of device-ids don't use old
metadata with a new device.

* xinput 2 documentation describes support for multiple master
devices. I believe this implementation will support that, since now it
just uses `DeviceInfo` from slave devices. The concept of master
devices is only used in registering for events.

* Uses popcount+bit masking to resolve axis indexes, instead of
iterating bit indices.

Licensing

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.
