Closed requested to merge verdre/gnome-shell:alt-tab-dynamic-thumbnails into master
Replace the allocation and positioning of thumbnails with a more modern vfunc override based approach. Use this new layout to allow the thumbnails to have a dynamic height depending on the window height which looks much better and makes the alt tab switcher look less cluttered.
This MR is replacing !105 (closed).
Marked as WIP because this depends on the detect-title-changes branch being merged (!176 (closed)).
