[gimp/wip/Jehan/layers-dockable-refresh: 36/92] app: add an item visibility lock.




commit 4d608e6e179c62f9657faf7f2ac02bfb7c7d0e7f
Author: Jehan <jehan girinstud io>

    app: add an item visibility lock.
    
    Sometimes one may want to lock visibility of a given layer. This is very
    useful in particular when shift-clicking a layer visibility. In this
    case, it won't be included in the list of layer to update. This can be
    used for instance if you want some layers always visible (or always
    hidden) while setting exclusive visibility of some other layers only.
