Two news about our `TCastleWindow` class:

1. The `TCastleWindow` and `TCastleControl` are now (again) advised to be used through these simple names. 

There is no more need to use the names with `Base` suffix, `TCastleWindowBase` and `TCastleControlBase`. They are now just deprecated aliases to the simpler names without the `Base` suffix.

Underneath, this happened because of a [change I announced at the end of 2021](https://castle-engine.io/wp/2021/12/27/tcastlewindow-scenemanager-removal-of-a-deprecated-property-soon/): The old deprecated `TCastleWindow.SceneManager` and `TCastleControl.SceneManager` are now removed. They were causing complicated dependencies (in the end TCastleWindow / TCastleControl code should not deal with viewport/scenes specifics), and the assumption that “every window starts with a default scene manager” was unnecessarily complicating understanding of CGE, and even the name `SceneManager` was outdated (we call it just “viewport” since a long time). The deprecated `CastleWindowTouch` was also removed — just use `TCastleTouchNavigation`.

2. We now use a Unicode (UTF-16) version of WinAPI throughout our `TCastleWindow` backend on Windows. This fixes support for international characters in window caption and in native open/save dialogs.

This is yet another post when it was hard to find a screenshot expressing the API improvements 🙂 So here’s a rendering of [window glTF model from SketchFab, by Yury Misiyuk](https://sketchfab.com/3d-models/window-4e596e7530d749068fa0aba2902b63df) in _Castle Game Engine editor_. The window glass nicely utilizes the material possibilities of PBR, the reflections of a dirty/old glass are nicely realistic and completely dynamic. Here I show them with lights designed in CGE editor — a feature that is correctly in development.
