Mac + Glumpy + SDL2, sdl2.SDL_CreateWindow title arg TypeError: wrong type #314

Hi, I'm trying to get glumpy running under High Sierra (10.13.6), XCode 10.1, macports, yada, yada.
SDL2 2.28.3, glumpy latest git clone version.

Both "window = app.Window()" or "window = app.Window(title='My Glumpy Window')" end up with an error...

...
File "/opt/local/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/glumpy/app/window/backends/backend_sdl2.py", line 222, in init
self._native_window = sdl2.SDL_CreateWindow(self._title,
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ctypes.ArgumentError: argument 1: TypeError: wrong type

I see title=None in the Window class, can't figure out what sets self._title, but replacing self._title with 'Bob' gets the same error, as does None. However, "b'Bob'" works.

The fix: since title is being passed into Windows.init, how about adding...

if title is None:
title_bytes = b""
else:
title_bytes = title.encode('utf-8') if isinstance(title, str) else title

just before the SDL_CreateWindow call, and replace self._title with title_bytes.
