How can you do fractional rotation? Does it only work with x11 or is it also supported in wayland?
Rotating the display by a custom angle is possible through xrandr on X.org.
There's no Wayland protocol for custom angle rotation, and I don't expect anyone to create a protocol extension without a use-case.
My wild guess: Theoretically it should be possible for a compositor to support similar custom rotation, as applications simply draw to their surface (window), without knowing how and where it is displayed on the viewport (display).
But it might require quite a bit of work, depending on the project, so I don't expect to ever see custom rotation on anything besides smaller/niche compositors.

Puh-lease. It's Wayland; the devs fully and honestly expect every app developer (eg.: calc, Libreoffice, notepad.exe) to implement custom angle rotation on their own.
