Describe the Bug
Some of the Matlab API functions of the Supervisor return non-native Matlab array, e.g.:
https://github.com/cyberbotics/webots/blob/master/lib/controller/matlab/wb_supervisor_node_get_velocity.m#L6

Instead, their returned value should be converted to an array, e.g.:
https://github.com/cyberbotics/webots/blob/master/lib/controller/matlab/wb_supervisor_field_get_sf_vec3f.m

Hello, it would be great if you could add some 3d text models. Thanks in advance :-)

There's no TriangleGeometry class in Three.js, but here's some ways we can implement one using the THREE.Triangle math class.

It shouldn't be visible, or at least moved around to not confuse editor users.

Potential undefined behaviour and deprecated Actor copy constructor generated
When letting the compiler generating the implicit destructor of OvCore::API::ISerializable, by defining a custom destructor in a derived-class and finally by letting the compiler implicitely generating a copy constructor for this derived-class by itself; then the copy constructor automatically generated is depreca
