To me, it looks very hard. The color mapping is done first, in python, 
and not repeated with every draw. The interpolation is done by agg at 
rendering time. Logically, I don't know any reason why agg shouldn't do 
what you suggest: interpolate the scalar field and then convert to rgb. 
 Maybe agg can do it this way. If so, it would still take quite a bit 
of work by someone comfortable with agg (i.e., not me) to make the change.

The interpolation algorithm used in imshow() can produce spurious
results, as has been noted before:
http://article.gmane.org/gmane.comp.python.matplotlib.general/12062
This happens because the data is converted to RGB before the
interpolation/resampling, rather than after. How hard would it be to
reverse this so that the data array is first interpolated & resampled
and then converted by cmap to RGB?

I'm seeing that too -- added a couple of hacks to fix it

Dang that looks good. The only glitches that I see are:
1) after the ">>> hist(x, 100)""" line in the Python pre-formatted text
box, there's an extra line's worth of vertical space.
2) The heading "Plotting commands" overlaps slightly with the top line
of the following table.
This is on Firefox 3 with Ubuntu 8.04.

I just took the plunge and pushed the beta website live. We are now
purely driven off the sphinx living in the doc dir.
There is still plenty of material from the old site (stuff from the
FAQ, the credits, stuff from the user's guide, goals/known issues) so
once again please feel free to contribute. It's much easier now that
it is plain rest and sphinx. One area where all developers can easily
contribute is by extending the FAQ when we get common questions on the
mailing lists. I would also really like to see sections on contours,
images and colormaps, colorbars, time series plotting (eg the spectral
stuff), collections....
 http://matplotlib.sourceforge.net
Let me know if you find any problems.

Attached is my current version of the patch. I've moved all of the
properties-copying stuff to collections, which makes the changes
legend.py more clearer (but I'm not fully happy with the patch and
haven't commit anything yet)

I found a few typos in artists.rst. Added a patch (don't want to commit
it, because I'm not actively working on the docs)
The first sentence of the section "Object containers" also needs to be
fixed (or I don't understand it):
 "Now that we know how to inspect set the properties of a given object
we want to configure, we need to now how to get at that object."
"inspect" or "set" ???

Don't worry about it -- I am going to try and revert these changes
with a thinner logo. I'll let you know when it's ready for testing.

I tried this, and it put matplotlib and home together, but on the line
below the icon. I tried to make sure there were no spaces between the
image and the start of the matplotlib word, but wasn't able to kill
the newline
firefox 2.0.0.14 on solaris x86

Nope, I'm not seeing this, even when I shrink the window width way down.
This is Firefox 2.0 on RHEL4.
Does putting a   between matplotlib and home help?

I am having problems in that the "matplotlib home" text is getting
wrapped with the new icon. Screenshot attached. Are you not seeing
this?
I may work on a thinner default logo, because I like having the

Indeed they do. 
http://matplotlib.sourceforge.net/doc/html/index.html links to
http://matplotlib.sourceforge.net/doc/html/goals.html which doesn't
seem to exist yet.
I guess this is temporary, but thought it worth pointing out.

Thanks -- all bug reports welcome because I may not be aware of them.
The goals page is horribly out of date so I am just going to scrap it
for now. We can resurrect it later if need be.

Googling suggests this occurs when the developer doesn't have write 
permissions (not the case here), or using http rather than https (also 
not the case).
Filed a bug here:

I did -- and since others are now adding comments that they see the
same, it looks like a generic sf problem. Hopefully they will get it
sorted out soon.

I'm happy to do use a smaller logo on the doc pages, but off hand do
not know how to do it. I am knee deep in trying to convert the
existing docs, because as you probably gathered the sphinx docs will
soon entirely replace the existing web pages entirely. So if you
could help with this logo change that would be great. Either route
(smaller logo or single icon) is fine by me.....

The new stylesheet for the docs looks great, John!
One extremely minor nit: perhaps the logo is a too large in this 
context. On smaller screens, like a 1024x768 laptop, it encompasses 
about a third of the usable browser window space.
Would it be possible to keep it the current size for the main home page, 
but use a smaller version for the documentation pages? Or, to the 
extreme, just use a small icon-sized logo like in the Python 2.6 docs?
