One way to show image properties

Eye of GNOME currently offers three different methods for a user to see image properties:

1. Status bar
2. Side pane
3. Properties dialog

This is problematic for various reasons:

• It clutters up the primary menu.
• It isn't clear to users which option they should use.
• It prevents us from properly improving the design of the image properties experience (because which one is it we're developing?)
• It allows users to clutter up the UI with multiple overlapping options (say if the status bar and side pane are displayed at once).

I don't believe that it's the user's responsibility to configure their apps properly. It's our responsibility to provide a sane set of high-quality options, which don't degrade the user experience.

We should pick one option (probably the side pane) and drop the other two.
