Drop-in replacement for Electron's BrowserWindow with working aspect ratio on
Windows.

The module addresses this Electron issue:
https://github.com/electron/electron/issues/8036.

> **Warning**: this package extends BrowserWindow, that approach doesn't work
  properly with some Electron API,
  [more here](https://github.com/electron/electron/issues/23#issuecomment-1961324).
  Underline code can still be used to implement custom Window class that
  doesn't extend BrowserWindow but keeps reference to it (idea for next version
  of this library!)

## Installation:

```bash
npm install --save electron-aspect-ratio-browser-window
```

## Usage:

```js
const AspectRatioBrowserWindow = require('electron-aspect-ratio-browser-window');

// AspectRatioBrowserWindow instead of BrowserWindow:
const mainWindow = new AspectRatioBrowserWindow({
  width: 800,
  height: 450
});

// Aspect ratio works on Windows, Linux, and Mac:
mainWindow.setAspectRatio(16 / 9);
```

## Try example:

```bash
git clone https://github.com/antonfisher/electron-aspect-ratio-browser-window.git
cd electron-aspect-ratio-browser-window/example
npm install
npm start
```

## Features:

- utilizes Winuser.h resize hook: https://docs.microsoft.com/en-us/windows/win32/winmsg/wm-sizing
- supports different screen scales: 100-125-150% setting on Windows.
