[yt-dev] off axis projection in yt-3.0

[nick moeckel]

If I give it a center of [.25, .25, .25], and width of 0.5, then the
rendered part of the plot appears centered and the right size. Labels on
the axes are then off by that factor of 2.

I'll have to mess around with this more tomorrow though, it's the end of my
functioning for tonight.
