SVGTextQuery.cpp local file with changes from Blink Commits

Change in `SVGInlineTextBox.cpp`:

bool SVGInlineTextBox::mapStartEndPositionsIntoFragmentCoordinates(const SVGTextFragment& fragment, unsigned& startPosition, unsigned& endPosition) const
{
    int fragmentOffsetInBox = static_cast<int>(fragment.characterOffset) - start();

    // Compute positions relative to the fragment.
    startPosition -= fragmentOffsetInBox;
    endPosition -= fragmentOffsetInBox;

    // Intersect with the fragment range.
    startPosition = std::max<unsigned>(startPosition, 0);
    endPosition = std::min<unsigned>(endPosition, static_cast<int>(fragment.length));

    return startPosition < endPosition;
}

and attaching 'SVGTextQuery.cpp' file with all my changes from this.
