tex_demo.png

Hi folks,

Just checked out mpl from CVS; tex_demo.py fails because it
cannot find tex_demo.png, which I know was in there a day or
so ago. Browsing on the SourceForge CVS portal, it isn't
shown there, so I don't think my CVS ignorance is behind this.
But it may be---let me know if you think so!
