1 For information about GNU Emacs and the GNU system, type C-h C-a.
2 Type C-c C-c to view the image as text
3 Use +, =, -, 0, C-+, C-=, C--, C-0 for further adjustment [5 times]

The above 5 attempts to enlarge at fullscreen does nothing.

I see the svg image resize automatically at fullwidth from default frame
size to 50-percent of fullscreen, toggling back to default frame size
will automatically shrink the svg image file.

As attached below, I see two SVG libraries for GNOME installed but my
emacs is linked to LUCID X toolkit.
