Looks like it has:

Last I checked if I recall correctly, about a year ago, the PS backend
merely dumped a raster image and didn't do real vector graphics. Has
this changed?

Just as a note, if you have Cairo, you have PS, PDF, SVG, raster, and, 
indeed, native draw-to-the-screen functionality.
They're not all robust and complete, but it's seeing a lot of 
development. A robust, numpy-aware PyCairo would be really nice.
In short, Cairo has essentially the same goals (plus a few more) as 
Kiva, except it's written in C. There's some discussion of using it in 
wxWidgets, and, of course, it's already used in newer GTKs.

Yes, this has been fixed.

Sorry to bother you again, but I recently upgraded from 0.87.2 to 0.87.3,
and
cannot save eps files anymore. I get a 'subprocess' error.
I am running Python 2.3, mpl 0.87.3, and TkAgg (although that shouldn't
matter).
Error occurs whether using toolbar or savefig to save.
Here's the script and the errror. Has this been fixed in svn?

[<matplotlib.lines.Line2D instance at 0x01B50418>]
