just set the scene to be the same size as the view and keep the two in sync 
and you have no problems. this is a cleaner and less problematic way of 
achieving the same end.

the simple mechanism is to just save out the rendered pixmaps on exit and load 
from there. this is what we will be doing in Plasma::Svg. the icon cache that 
rivo is working on as part of his SoC project will come to good use here as 
well.

not sure you'll get a good ROI there, but it is your call =)

instead of loading a huge number of svg's, one per on screen element, i really 
recommend putting all the elements in one svg and rendering named elements. 
this makes it easier on artists, is faster to load and kinder on resources.
