McRogueFace needs to accept callable objects (properties on C++ objects)
and also support subclassing (getattr on user objects). Only direct
properties were supported previously, now shadowing a callback by name
will allow custom objects to "just work".
- Added CallbackCache struct and is_python_subclass flag to UIDrawable.h
- Created metaclass for tracking class-level callback changes
- Updated all UI type init functions to detect subclasses
- Modified PyScene.cpp event dispatch to try subclass methods
Demonstrates the object-oriented Scene API as alternative to module-level
functions. Key features tested:
- Scene object creation and properties (name, active, children)
- scene.activate() vs mcrfpy.setScene()
- scene.on_key property - can be set on ANY scene, not just current
- Scene visual properties (pos, visible, opacity)
- Subclassing for lifecycle callbacks (on_enter, on_exit, update)
The on_key advantage resolves confusion with keypressScene() which only
works on the currently active scene.
