Arthur O'Dwyer ced3bbcad4 Qualify calls to format
C++20 introduces `std::format` and we `using namespace std`,
so some of these would be ambiguous in C++20.

// A tool to create smooth manually controlled movement animations in 3D geometries.
// Press 'f' to start controlling
// 'qweasdzxc' will move the camera and additionally rotate the view a bit (except 's')
// 'b' goes back 1 frame, 'e' undoes 30 frames
// 'r' starts recording
// 1234 change movement speed (see console for details)
// 67890 change rotation speed (see console for details)
