curvelinear coordinate support in axes_grid and a possible refactoring of mpl.

Hello,

I recently committed a support for a curvelinear grid in the axes_grid
toolkit. What it does for you is to draw a ticks and grid appropriate
for a curvelinear coordinate system, as in the example below.

http://matplotlib.sourceforge.net/_images/demo_floating_axis1.png

The main motivation behind this work was to display astronomical
images with matplotlib. However, I included this in the axes_grid
toolkit hoping that this could be also useful in other fields.

The reason I'm posting this email is related to a possible refactoring
of the matplolib, that John once mentioned, to better support the
ticks and spines. To support the curvelinear grid, I had to create a
customized Axes class, and I believe that some of my effort overlaps
with the refactoring that John mentioned. In the linked document
below, I tried to describe the changes I made for this.

http://matplotlib.sourceforge.net/mpl_toolkits/axes_grid/users/axislines.html

I guess some of my idea or implementation may be considered to be a
part of the refactoring (if it ever happens :slight_smile: ). Or, at least, I hope
that the issues I had with mpl's current Axes implementation are
reflected in the refactoring efforts.
Well, I just wanted to toss around some ideas and hear what others think.

Regards,

-JJ

ps. Are we having a sprint during the scipy conference by the way? I
may join remotely.

I'll definitely be there Sat and Sun, so having you join in remotely
would be great. I haven't organized any official topics yet, but we
have plenty to do so I think we'll just look at the skills and
interests of those joining live or virtually and hammer away.

I'll be there, too. I think an MPL sprint would be very good.

Great -- give that we have JJ (remotely), you and me confirmed, two
obvious topics to work on are:

  * buildbot : JDH & Andrew

  * integrating JJ's curvilinear ticking w/ Andrew's spines

I'm up for anything else that people want to work on, but at least
we'll have the right people in the room, if only virtually, for these
topics. Anyone else planning on attending on-ground or on-line?

I’ll be there on the ground, though my flight leaves 1:50 on Sunday. We might also consider doing some discussions during the week, maybe a BoF?

Great, hopefully you can join us Saturday. If there is anything in
particular you want to work on during the sprint, let me know. As for
a BoF, I generally find discussions less useful than coding, since
python is such a great prototyping language, though there will be many
opportunities to brainstorm over beers, etc... Are there topics in
particular you have in mind?
