Subject: [PATCH] Restore transparency
The transparency settings were removed as a side effect of
2bff4b63ed3ceef6055e35563e9b0b33ad57349d
This restores them and you will need a compositing window manager to
use it. The background image setting, also known as faux transparency,
was not restored.

[PATCH] window: Make the drawing robust across all themes
There are lots of themes out there in the wild that do not specify a
background-color for all widgets and the default is transparent. This
is usually not a problem because GTK+ sets an opaque region on the
whole window and things without a background-color get drawn with the
theme's default background colour. However, to achieve transparency
we disable the opaque region by making the window app-paintable. This
can lead to transparent menubars or notebook tabs in some themes. We
can avoid this by ensuring that the window always renders a background.
