It think it would be very interesting to be able to add multiple files in 
the same zipped file.

This would allow including all external materials (images, sounds, fonts, 
…) needed by the svg file to render properly. The compressed format could 
be “tar gzip” instead of a simple “gzip”.

The main benefits are independency (all resources and the main svg file are 
located in a single file), and no more flickering (as soon as the file is 
completely loaded, every resources can be used right now). The main 
drawback is a longer loading time.

The loading time is longer because all resources are loaded before the svg 
rendering begins. This loading time could be optionally reduced to the one 
of the classic gziped file if the tar-gzipped file allows streaming (which 
I don’t know). Thus, if the main svg file is the first file in the tar, it 
can be rendered as soon as it is read, then the resources would become 
visible too as soon as they are read (but with the flickering effect).

Any opinion?
