TestComposeWindow

Kotlin |Java

android
```
class TestComposeWindow
```

A virtual window for testing purposes.

After setContent it composes content immediately and draws it on a virtual surface.

It doesn't dispatch frames by default. If frame dispatching is needed, pass appropriate dispatcher as coroutineContext (for example, Dispatchers.Swing)
