The work on LoD and animation continues in krita-animation-pentikainen
The branch is regularly merged into krita-animation-kf5-kazakov, which gets changes from master as well.
When animation gets a "zero-overhead disable" feature, krita-animation-kf5-kazakov is deleted and all the changes from krita-animation-pentikainen are merged directly to master. The work on LoD and Animation still continues in krita-animation-pentikainen because user testable packages are still built basing on Qt4 version.
