Diffs are usually easier to read, especially in MUAs that don't render
font attributes for HTML mails. If you want all of the previous code to
be included in the diff, you can just give a sufficiently larger number
to the -U option of git diff. I'll include an example below.


> from sugar.graphics import style

The "sugar" Python package is provided by the pyGTK + GTK2 based sugar-toolkit
package. If you want to use gobject introspection + GTK3, you need to
use the "sugar3" Python package which is provided by the
sugar-toolkit-gtk3 package.

Where does screen get defined? Do we need to load the theme from inside
each widget or can we do it once for an entire process?
