Api changes to PanelSvg finished:

Browse Source 
-now it's a Plasma::Svg
-DrawTopBorder DrawLeftBorder etc -> TopBorder LeftBorder etc
-contentAtOrigin -> out of flags
-setFile() -> setImagePath()
-setBorderFlags() -> setEnabledBorders()
-added resize(qreal,qreal)
-setPrefix() -> setElementsPrefix()
-updateSizes() -> Q_PRIVATE_SLOT
-pos() setPos() removed, now pos is a parameter of paint
-setLocation() -> setElementPrefix(enum)
-location() removed
