Ticklabels in scientific notation comes out wrong in the pdf backend


Saving a semilogy plot using the odf backend the exponents come out wrong. As can be seen in the attached png file pdf-backend.png the exponents are printed as a subscript and also with the lowest value at the top of the axis, 10e-3 is at the top and 10e3 is at the bottom. See t-pngbackend.png for the behaviour I get with a png backend.

Looking at the source for the pdf-backend I also saw that it contains a mix of space and tabs for indentation.

Keep up the good work, I'm looking forward to using 0.9 when the win32 binary is out.
