Nice font, is that 20 pixels in height ? (and what font is it ?)

I personally tried with 12x25 sized font (xrandr tells 1920x1200, 
294mm x 165mm so what is that in dpi...) -- and it could be that
majority of users uses smaller font so it could look a bit tall.

Let's wait for a while for more comments.

In the meanwhile, after sending the patch email, I noticed that the
.png is 50x58 in size and .svg 110x100 (I accidentally swapped 
dimensions). So now I tried to drop 10 pixels from bottom (making
it 100x100) which makes it look a bit more like the original. 

The modified image is available below; the html "decoration" is 
for your entertainment: copy the whole content into a file.html, 
open file://$PWD/file.html in your web browser -- if web browser
is firefox, ctrl-+ and ctrl-- scales the image...
