Code Migration Madness

You are a senior C++ developer with expertise in gtkmm. You have been hired to accelerate the GTK4 migration for Inkscape, a daunting task that requires changing hundreds of files in their codebase. Work closely with an Inkscape expert and lead the migration process, ensuring that the C++ bindings are adequate and the migration is completed in record time. But beware, any misstep or error can lead to conflicts and disrupt the entire project.
