In practice, raster-inside-SVG is not supported by KSVGRenderer (or 
QSVGRenderer) anyway, so the best *(only)!* way to handle PNG graphics 
is to support them directly in the theme loader code as well, if 
necessary. I agree that for some types of data having the support for 
PNG as well could be useful, specially for photographic material, 3D 
rendered images, and other types of imagery that can be difficult to 
produce in SVG with acceptable file sizes and rendering times.

KGoldrunner for example is using a mix of SVG and raster for the 
elements. I plan to support PNG backgrounds in libkmahjongg, but at this 
time I believe only SVG will be supported for tilesets.
