Re: [matplotlib-devel] a patch to have a correct baseline when usetex=True

Sphinx contains one way to do this in its new "pngmath" extension.  It 
uses the LaTeX package "preview" which does all of this magic 
internally.  And I believe it's a little more general.  If I recall, the 
approach you're taking won't work with some LaTeX constructs such as:

  \begin{align}
     x & = 2
     y & = 2
  \end{align}

Plus, Sphinx is BSD-licensed, so it should be fine to copy-and-paste 
whatever code is necessary.

Of course, latex-preview is required to be installed, but I think it's a 
pretty common package.

See here:

Cheers,
Mike
