GTK4 Migration Boss

As the newly hired senior C++ developer with experience in Gtkmm4, you are tasked with migrating Inkscape's codebase to GTK4, ensuring that the C++ bindings (Gtkmm, Pangomm, Cairomm, etc.) are adequate. To achieve this, you will work closely with an Inkscape expert with intimate knowledge of the codebase. Your goal is to complete this migration within 16 weeks while managing a team of developers, setting deadlines, and staying within budget.
