HttpAsset and Google Fonts

I've encountered an issue when using Bootstrap 4 and Bootswatch Themes. Some themes do an @import loading Google fonts.

Warning: file_get_contents(https://fonts.googleapis.com/css?family=Lato:400,700,400italic): failed to open stream: Es konnte keine Verbindung hergestellt werden, da der Zielcomputer die Verbindung verweigerte. in \vendor\kriswallsmith\assetic\src\Assetic\Asset\HttpAsset.php on line 57

I am going to change / extend the code to use curl instead... has anyone already done it?

This works for me:

public function load(FilterInterface $additionalFilter = null)
{
    if(function_exists('curl_init')) {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_HEADER, false);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
        curl_setopt($ch, CURLOPT_URL, VarUtils::resolve($this->sourceUrl, $this->getVars(), $this->getValues()));
        curl_setopt($ch, CURLOPT_REFERER, VarUtils::resolve($this->sourceUrl, $this->getVars(), $this->getValues()));
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
        curl_setopt($ch, CURLOPT_PROXY, '<proxy>');
        curl_setopt($ch, CURLOPT_PROXYPORT, '<port>');
        $content = curl_exec($ch);
        curl_close($ch);
    } else {
        $content = @file_get_contents(
            VarUtils::resolve($this->sourceUrl, $this->getVars(), $this->getValues())
        );
    }

    if (false === $content && !$this->ignoreErrors) {
        throw new \RuntimeException(sprintf('Unable to load asset from URL "%s"', $this->sourceUrl));
    }

    $this->doLoad($content, $additionalFilter);
}

As I am behind a proxy, I'd like to add appropriate options. Where should they be placed? AssetFactory.php? Function setProxy()?
