Use SVG plots in OctaveMagic by default due to lack of Ghostscript on Windows Octave

[blink1073]

Newer builds of Octave on Windows do not include Ghostscript, and do not support printing PNG files out of the box. I suggest making the default SVG files, which is supported.

As of now, a user would have to follow the instructions here to enable support for PNGs:

http://wiki.octave.org/Octave_for_Windows#Printing_.28installing_Ghostscript.29.

I think the fix is reasonable... others thoughts?

[ivanov]

If this is a change that only applies to windows, I'd prefer it delineate itself as such (something like if sys.platform == 'win32' set it to SVG, but keep it as PNG otherwise.

[damianavila]

I agree with you...

@blink1073 can you update the PR taking into account the @ivanov's comment?

[blink1073]

Done.

[ivanov]

thanks for your contribution! eventually, we'll be moving the octave magic out of ipython proper, but hope this little change helps your fellow windows users in the meantime.

May I ask why? I am the author of oct2py.

The point of extensions is that it is possible to add functionality to IPython from code outside IPython. It doesn't make sense for IPython to be responsible for maintaining the language extensions (cython, R, and octave are all to be removed, only R has actually been taken up elsewhere thus far), nor does it make sense to bind the extensions to IPython's release cycle.

[rossant]

Where will these language extensions be eventually?

[ivanov]

in their own respective projects (the R one was already moved to rpy2, for example). Follow #3803 for more on this.

Roger, I will absorb octavemagic into oct2py following the rpy2 model.
