Color transparency bug

Summary:

3 Ellipses:

• background one as a drop shadow = 100% opacity
• foreground ones as a 3D button = 100% opacity

As a result, if you move the background one, the foreground ones colors change although they where 100% opacity or not having alpha channels.

Steps to reproduce:

• open Inkscape
• Load the SVG f
• Move the background shadow ellipse and watch how the green button appears to be transparent.

What happened?

The button colors changed as you move the shadow.

What should have happened?

As the button is opaque and no alpha and transparency, the colors must maintain while the shadow are moved.
