Hullo List,
This patch adds a "clock" style progress, so one doesn't have to mouse
over the Zenity icon to see where it currently stands.
Very simple, very rudimentary, but already summat useful for me. Hope
others find it so as well.

Subject: [PATCH] Update Zenity with progress icon notification
Add a "clock" style progress meter for the build via dynamically
generated svg images. The colors are rather arbitrarily chosen, but
with a very minor attempt to be readable by color-blind folks. A second
round cut of this patch might make the fill and stroke colors
configurable.
