#479 SVG text parser should "push" the style for "tspan"

[christian deligant]

if an SVG image contains text and inside the text you have a tspan item, ALL the tspans are printed at the (0,0) location of the image.

Because text and tspan tags act as containers, I suggest this modification in the startSVGElementHandler function, in the switch section (=> is added, > is changed)

        // text
        case 'text':
        case 'tspan': {

=> array_push($this->svgstyles, $svgstyle);
// only basic support - advanced features must be implemented

          $x = (isset($attribs['x'])?$this->getHTMLUnitToUnits($attribs['x'], 0, $this->svgunit, false):$this->getx());
          $y = (isset($attribs['y'])?$this->getHTMLUnitToUnits($attribs['y'], 0, $this->svgunit, false):$this->gety());

and obviously adding this line (marked by =>) in the switch of the endSVGElementHandler function

            // restore previous rendering mode
            $this->textrendermode = $textrendermode;
            $this->textstrokewidth = $textstrokewidth;
            $this->svgtext = '';
            $this->StopTransform();

=> array_pop($this->svgstyles);
break;
}
default: {

OK. Fixed on TCPDF 5.8.030 with some changes.
