Close the 19,000+ leaks introduced during the DOM merger

The attach patch closes all known leaks in WebKit+SVG.

The patch also includes a (necessary) optimization to KCanvasContainer::paint() and (RenderPath::paint()) 
to not push a new KRenderingDeviceContext onto the context stack if one has already been pushed.  Not 
adding this optimization was causing CGContextBeginTransparency layer to have kittens... I was never 
able to fully understand why, except that the transparency layer methods, as part of their silent context 
swapping, seem to assume a certain CGContextRef, CGContextRelease pattern which we don't seem to 
follow, even though my previous code seemed perfectly legal.
