Fixes#16783
Works around a `cosmic-text` bug or limitation by triggering a re-layout
with the calculated width from the first layout run. See linked issue.
Credit to @ickshonpe for the clever solution.
This has a significant performance impact only on unbounded text that
are not `JustifyText::Left`, which is still a bit of a bummer because
text2d performance in 0.15.1 is already not great. But this seems better
than alignment not working.
||many_text2d nfc re|many_text2d nfc re center|
|-|-|-|
|unbounded-layout-no-fix|3.06|3.10|
|unbounded-layout-fix|3.05 ⬜ -0.2%|2.71 🟥 -12.5%|
I added a centered text to the `text2d` example.
`cargo run --example text2d`
We should look at other text examples and stress tests. I haven't tested
as thoroughly as I would like, so help testing that this doesn't break
something in UI would be appreciated.
