0.79 MB (on the squashfs) is for XML files only, and is HIGHLY
error-prone due to applications either not recognising whitespace
properly, not recognising the <?xml?> declaration, not recognising the
encoding, parsing using a homegrown parser or regex that relies on
indentation/pretty-printing, or just being finnicky.

But the Ubuntu LiveCD still stands to gain an easy 11 MB, even without
that 0.79 MB. :)

5 MB (on the squashfs) for PNG images: completely safe conversion,
because OptiPNG doesn't have bad bugs.

6 MB (on the squashfs) for SVG images: completely safe conversion
except for the card games, which need ID names to seaprate the cards
from the one SVG file. All application icons and user interface button
icons etc. are okay.
