`CharacterBitmap` instances are generated at run-time and put on the heap, but they can be created in a `constexpr` context and stored in static memory. Also, remove additional `width` and `height` `static` values in favor of using the `constexpr` member functions of `CharacterBitmap`. These changes also include the removal of some initialization code which tests if the `CharacterBitmap` is created since it is always created and removes function-local `static` values which cause run-time branches to ensure it is initialized each time the function is called.
