1. Only import matplotlib when needed …

   Some tests and one bit of library code were importing matplotlib
   even if plotting was not requested. This could cause needless failures
   (not to mention unwanted rebuilds of the font cache).
   
   I standardized the following:
   - Only import matplotlib when plotting is specifically requested.
   - Library code logs a warning and continues if importing matplotlib
     fails. One bit of code did that already, but printed a message
     to stderr instead of logging the message.
   - Unit tests raise an exception if importing matplotlib fails.
     This is reasonable because you have to modify a test to make it plot.
   - `import matplotlib.pyplot as plt`, as per our coding standards.
