Increase the default project window size for better usability

The new default window size is tuned to:

- Have a 16:9 aspect ratio,
- Have both dimensions divisible by 8 to better play along with
  video recording,
- Be displayable correctly in windowed mode on a 1366×768 display
  (tested on Windows 10 with default settings).

This breaks compatibility with projects that didn't change the
window size from the default value (or that kept one of the values
to its default).
