    looks like QPainter include could be removed

    are you sure that you can delete the texture here? Is the object being destroyed from the rendering thread?

    nitpick: looking at the surrounding coding style the * should be moved from type to name



src/declarativeimports/core/svgitem.cpp
<https://git.reviewboard.kde.org/r/115923/#comment35466>

    nitpick: Q_UNUSED doesn't need a ;



src/declarativeimports/core/svgitem.cpp
<https://git.reviewboard.kde.org/r/115923/#comment35463>

    I never really understood who takes ownership over the nodes: does one have to delete the oldNode?

    Q_NULLPTR



src/plasma/svg.cpp
<https://git.reviewboard.kde.org/r/115923/#comment35464>

    nitpick: empty lines
