Bojan,
Thank you for the suggested patches. Unfortunately, however, they do 
not in general solve the problem of size mismatch between the colorbar 
and the corresponding axes, as you will see if you try a variety of axes 
dimensions and aspect ratio settings. Your patch is equivalent to 
setting the default shrink to 0.8 instead of 1.0, and I agree that this 
is a better default. I did not use it originally simply for the sake of 
backwards and Matlab compatibility. I suspect that making the change 
will please more people than it will upset, though, so I will try it in 
svn after the switch to the transforms branch. I don't see any point in 
making little changes like this right now, when we are trying to 
stabilize a last release before that switch. Everyone has lived with 
the present default for a long time, and a few more weeks won't hurt.
A more general solution to the size-matching problem may emerge after we 
switch to the transforms branch, but to my mind it is fairly low priority.

Hello,
first let me thank you for your excellent software - I think
it is just wonderful and very pleasant to use.
Two small things came up when I installed 0.91.1 into
my home directory (I didn't want to mess with the debian
packages since they are usually very fast in updating them)
This passage in the INSTALL file is misleading:
Note that if you install matplotlib anywhere other than the default
location, you will need to set the MATPLOTLIBDATA environment
variable to point to the install base dir.
Instead of setting MATPLOTLIBDATA to the base dir I specified
with setup.py install --prefix /home/mo/mpl I had to set
it to
/home/mo/mpl/lib/python2.4/site-packages/matplotlib/mpl-data/
for mathtext to find its fonts.
Secondly this passage in matplotlib/mathtext.py
 544 if cached_font is None:
 545 try:
 546 font = FT2Font(basename)
 547 except RuntimeError:
 548 return None
Where an unfound font file is not reported but rather a None font object
is returned just causes a Null pointer exception to be raised very
shortly afterwards without the important info as to the
real reason. Maybe the RunTimeError should just be raised as is
or handled in a more informative manner?
Thanks again and sorry for my nitpicking,
Mario Oschwald

Eric, since you wrote the shrink code, I'll leave this one up to you...
