Add an example to test small window sizes (#3597)

# Objective

We keep getting issues where things break at small window sizes, e.g #3368 (caused by #3153), #3596 ('caused' by #3545)

## Solution

- Add a test that we can make small windows.


Currently, this fails on my machine with some quite scary vulkan errors: 
```

```
etc.

This might be a new issue here, although I'm surprised it's vulkan giving this error; wgpu should stop it if this is illegal.
