Where is the background of the Unity (3D) launcher located? I would like to enhance the transparency of the launcher to make it fit better with light themes (such as Radiance). The actual transparency of the launcher suits only with darker themes (like Ambiance).
The file "launcher_background_middle.png" in /usr/share/unity/themes doesn't seem to affect the launcher transparency, and I haven't yet found out where the launcher background is. It should be a picture that can be edited with Gimp.
Thanks in advance for your help.
