Speaker icons for gnome-media

We're looking to add speaker testing support to gnome-media. For that, we'd need a few bits of artwork.

• 2 speaker icons. Only need one size, as SVG. One for an "off" speaker, one for a playing speaker. If the artist(s) wants to have better perspective, then they'd need to provide more icons. The example UI link below show the worst case scenario (7 speakers and a subwoofer).
• 2 subwoofer icons. same as above.
• 1 icon for the user (it is thought that it would be best to show the user at her computer, to humanise the process)

Possible combinations:

• Mono
• Stereo
• 4.0 (4 speakers)
• 4.1 (4 speakers and a subwoofer)
• 5.0 (5 speakers)
• 5.1 (5 speakers and a subwoofer)
• 7.1 (7 speakers and a subwoofer)

The current "user" icon looks like this smiley but should look more like the one in this mockup
