Progams code for a certain layer type is encapsulted within a dedicated `<layer type>Programs` class, inherited from the generic base `LayerTypePrograms` class. `mbgl::Programs::get<layer type>Programs()` lazily initializes the layer type-specific programs code using pointer to the base class, which allows LTO to remove this code from binaries (if the corresponding `get<layer type>Programs()` method can never be invoked).
