Cursor types and cursor-shape-v1 support

[alebastr]

• Support for different cursor types.
  Testable with rofi -theme docu ....
• Support for compositor-rendered cursors via cursor-shape-v1.
  Requires wlroots >= 0.17 (Sway v1.9 or master branches) and wayland-protocols >= 1.32.
  For an extra rice, do

  seat seat1 {
    attach a-second-pointer-device
    xcursor_theme non-default-theme
  }
  

  and observe two cursors with different themes.

Also fixes #105

With that in place, I was prepared to tackle the final boss, fractional-scale-v1... but my holiday time off has ended.
I'll try to finish it in the next few weeks, but no promises.

@alebastr
Thanks for looking into this :)!

One thing though, I have tried with two cursors of different sizes and they both get resized to the value of $XCURSOR_SIZE when hovering over rofi. But I guess it's another existing issue?

This works for me with swaywm/sway@2bba8a8 (branch v1.9) and different cursor sizes per seat (seat seat1 xcursor_theme default 36).

With client-rendered cursors, it's an expected behavior to have the same theme/size for all the seats (inherited from the default seat0 at least in Sway), as there's no standard way to pass a per-seat configuration from the compositor. You can check if the cursor-shape-v1 protocol is used with WAYLAND_DEBUG.

Ah well ok 😁

Thanks!
