Visualizations don't work well with dual-screen

[PEIGNOT Kévin]

Hi

There is a bug when you're listening music with Totem and want visualizations in full screen if you're on a dual screen setup :

 - What happenned :
Visualisation format is very large an not very high. It like if it added the two resolutions of the screens. But if you go full screen, it covers only one screen. So you have a band of color, with two black bands up and down (and probably on each side if your monitors are configured up/down). This is not full screen.

- What I expected :
I expected my full screen visualisation to fill all my screen (the one I made the visualisation full screened, the projector in my case), not having only a band

- How to reproduce : Simple :
In a mono-screen config, play an audio file with totem and visualisations activated. Make vusalisation full-screen. Then do the same thing with dual-screen. You understand immediately the problem (easy to see on the attached screenshot)
