Code Migration Accelerator

You play as a senior C++ developer hired to perform essential steps in the GTK4 migration for Inkscape, including ensuring the adequacy of C++ bindings such as gtkmm4, pangomm and cairomm. Work closely with an Inkscape expert with intimate knowledge of the codebase, while consulting multiple senior developers during the 16-week project. Maintaining a high level of progress is vital due to the urgency of the migration. Do you have what it takes to accelerate the code migration within the given timeframe?
