Tweak SSAO depth calculation in vispy backend #43

This is what I see right now on Windows.

Seeing jaggies with SSAO and not FXAA on is expected (since the automatic antialiasing from the opengl driver gets disabled), but that doesn't look like it's computing anything at all. Is that file somewhere so I can compare with linux?

After chatting with Bradley offline, that particular issue was due to z-fighting for a large scene. I don't think SSAO use is very prevalent right now, so this change can only improve things. I'll go ahead and merge.
