GTK4

As the GTK3 and gtk-layer-shell crates are now deprecated, there is a need to move to GTK 4.

The refactor/gtk-4 branch and PR #112 are tracking the code upgrade. This page documents the port progress.

Assistance in the porting process is very much welcomed, no matter how small.

As many modules have not been ported, the default feature set will fail to compile. It is therefore necessary to compile manually with --no-default-features, enabling only the working modules:

cargo run --no-default-features \
  --features config+all,clock,cairo

A full list of feature flags can be found here.
