Anthony Eidandlingyaochu d18060e16a git_graph: Fix height realignment issues (#54429)
Special thanks to @lingyaochu for finding out the root cause of the
issue.

Took the test from: https://github.com/zed-industries/zed/pull/54233 

The git graph was using `buffer_ui_size` when calculating the canvas row
height and the table row height. This is wrong because elements such as
`Labels` in the graph table were rendered using `ui_font_size`. This PR
normalizes the row height calculation by always using `ui_font_size` for
the canvas and table row height calculation, and taking into account the
scaling factor.

This PR also fixes a bug where the bottom of the canvas could flicker on
its first redraw because the uniform list hadn't cached the viewport
size yet, and we underestimated the visible size of the canvas and
underdrew it. We now fallback to the window height as the viewport size.
This means we'll overdraw for a single frame whenever the uniform list
hasn't cached the last item size, but it avoids the flicker!

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.
