Inkscapes: The GTK4 Migration

You are the new senior C++ developer with GTK experience hired to perform essential steps in the GTK4 migration for Inkscape. You will be responsible for ensuring that the C++ bindings (gtkmm, pangomm, cairomm, etc.) are adequate over a four-month time period. You must work closely with an Inkscape expert with intimate knowledge of the Inkscape codebase to ensure the migration is completed as quickly as possible. The results of your work will significantly improve the performance of the user interface and the canvas. Can you handle the pressure and successfully manage this complex endeavour?
