Messy ouput because QSvgHandler ignores whitespaceMode hierarchy

When trying to paint an CorelDraw generated vaild SVG image with QSvg the leading whitespaces of text-Items are skipped even xml:space="preserve" is globallly set in the svg-tag.

svg sample:
<svg xml:space="preserve" ...>
...
<text x="23.0529" y="150.829" class="fil3 fnt7"> in my house</text>
...
</svg>

My suggestion is to change the code in qsvghandler.cpp at line 3436 as follows:
if(xmlSpace.isNull())
{
// This element has no xml:space attribute.
// Inherit the whitespace-Mode from parent element if exists
if (m_whitespaceMode.isEmpty())
m_whitespaceMode.push(QSvgText::Default);
else
m_whitespaceMode.push(m_whitespaceMode.top());
}
