Variable to change color of watermark text

[Ian-Robinson1]

Please describe the new functionality as best as you can.

The watermark text color cannot be changed with a variable when a pdf is created. Currently, the only way to change it is to directly edit src/Mpdf.php line 10598, such as:

$this->SetTColor($this->colorConverter->convert(0, $this->PDFAXwarnings));

To:

$this->SetTColor($this->colorConverter->convert('red', $this->PDFAXwarnings));

Being able to change the color with a variable would be very helpful

Here is a possible solution, please add it to next patch/version. @finwe

1. Need to define the variable:

var $watermark_color;

2. Set default in _construct:

$this->watermark_color = 0;

3. Create setter function

function setWatermarkColor($watermark_color = 0){
$this->watermark_color = $watermark_color;
}

4. Use variable in line 10484

$this->SetTColor($this->colorConverter->convert($this->watermark_color, $this->PDFAXwarnings));

@v1har Why don't you propose a pull request directly?

But rather than stomping more and more public properties to the Mpdf class, why not introduce a method

public function setWatermark(Mpdf\Watermark $watermark): self

with the Watermark object containing all details of the watermark?

@finwe I am not a pro user of github so I thought it's easier to tell you the idea so you can implement / add pull request. I just tried to help because I need this functionality too. :)
