Maybe not. If you use a latex centering environment, I think the figure is=
=20
centered. Even in a centering environment, it may still appear to be off=20
center, since the axes+labels may not have been centered in the figure wind=
ow=20
in the first place. =20

This really is fixed now, for both horizontal and vertical alignment.

This is expected behavior for PSfrag. You should instead wrap \includegraph=
ics=20
in either a \resizebox or a \scalebox to rescale the text with the figure.=
=20

It looks like tex_demo.py, without caching, takes about 30% longer with LaT=
eX=20
than it does for Tex (3 seconds vs 2.3 seconds on my computer). So CVS is=20
back to using TeX. We may want to include a link (or a copy) of this pdf on=

the MPL website: http://www.csit.fsu.edu/~mimi/tex/tex-refcard.pdf, the=20
source declares it to be freely distributed.
