Use byzanz to create a GIF screencast of a specific window.

Required tools:
sudo apt-get install byzanz x11-utils xdotool

A tip: use an extra-long duration (-d 100), record your shot, and use
gimp to shorten the duration of the last frame. You need to rename the layer
from "Frame 123 (100000 ms) (combine)" to "Frame 123 (1000 ms) (combine)".
