Including scalable icons to improve size coverage

Today I looked at shipping svgs with echo-icon-theme to
improve the
coverage and avoid size gaps where we don't have hand-tuned
small sizes
yet. 

Unfortunately, doing this blows up the size of the tarball
to 70M (after
bzipping !). Looking at some of the large (>500k) icons,
I notice a
couple of things:

a) they seem to mostly be created with Illustrator

b) they include a jpeg thumbnail

c) they include a huge binary chunk called  
   <i:pgf id="adobe_illustrator_pgf">


It would be very valuable if someone could work on a little
script to 
get rid of the thumbnails and the illustrator-specific
stuff. That 
should allow us to shrink the svgs _a lot_ and make it
possible to
include them in the package, which is not possible as things
stand right
now.

I wrote the script you asked for. It removes the following
elements:
i:pgf (where the ID is "adobe_illustrator_pgf"),
i:pgfRef and xmpmet
a. 
Attached is a trimmed version of one of the icons (416k to
18k) . People 
should check it works on their svg tool before you start
compressing icons.

Thanks, that looks encouraging.

Thank you. I will try it later.

Great. That should reduce some tasks until these svgs icons
have their own png
small size. I am also considering some of them (especially
the 24x24 who are
identical to their larger formats).

Surprising. Maybe converting them using Gimp should do the
trick.

Which explains longer loading page.

I've used Charlies script and included svgs in yesterdays
echo snapshot.
Please give it a try.
