Mike,
I have fixed all but one test--in some cases, partly by fixing tests 
and/or the baseline images.
The one exception is figimage. I don't think I have changed anything 
that would affect that in any obvious way, but certainly I could be 
wrong, and I haven't looked into it. The immediate problem is that I 
can't see what the difference is between the baseline and what I am 
generating now. They look identical to my eye, on my screen. The diff 
plot shows up as a black square. The png files are different, differing 
in length by 2 bytes, so something has changed--but what? Given that I 
can't *see* any difference, I am tempted to just change the baseline 
plot so that the test will pass, but maybe that would be a mistake.
Building mpl from a version 2 months ago, I am still seeing the figimage 
failure.
