遇到的问题：
1.水印无法平铺，解决办法：
文字水印：
找到 Mpdf.php 中的 watermark 方法，
把
$this->Text($wx, $wy, $texte, $OTLdata, $textvar);
修改为：
//平铺文字水印
$this->Text(-50, 200, $texte, $OTLdata, $textvar);
$this->Text(0, 150, $texte, $OTLdata, $textvar);
$this->Text(0, 250, $texte, $OTLdata, $textvar);
$this->Text(50, 100, $texte, $OTLdata, $textvar);
$this->Text(50, 200, $texte, $OTLdata, $textvar);
$this->Text(50, 300, $texte, $OTLdata, $textvar);
$this->Text(100, 50, $texte, $OTLdata, $textvar);
$this->Text(100, 150, $texte, $OTLdata, $textvar);
$this->Text(100, 250, $texte, $OTLdata, $textvar);
$this->Text(150, 0, $texte, $OTLdata, $textvar);
$this->Text(150, 100, $texte, $OTLdata, $textvar);
$this->Text(150, 200, $texte, $OTLdata, $textvar);
$this->Text(200, 50, $texte, $OTLdata, $textvar);
$this->Text(200, 150, $texte, $OTLdata, $textvar);
$this->Text(250, 100, $texte, $OTLdata, $textvar);

2.生成的pdf是“非标准格式”，解决办法：
$mpdf->useAdobeCJK = true;
$mpdf->autoScriptToLang = true;
$mpdf->autoLangToFont = true;
3.不支持元素display属性变化，不支持position定位
4.一个只包含中文符号的html标签（并非中文文字乱码），中文符号会变成乱码，我这里换成了7.1以上的版本，并且 new Mpdf(['mode' => 'zh-cn']) 设置了'mode' => 'zh-cn'，解决了这个问题
