SVG often includes raster images? That's very surprising to me. I can see some use cases here and there, sure, but using a vector format to 'often' include raster images... i dunno.

Thousands of XML elements is the ideal case, compresses extremely well.

An example, many of Inkscape's filters depend on raster samples that need to be embedded. Complex gradients are also rasterised.
