I started working on this, but then realized I would also need to add
it to buffer_argb32, buffer_rgba and so on, and that is was much
cleaner to simply add an im.flipud() method than implement it in all
the conversion and write methods.
I just committed changes with these fixes and updated backend_ps and
backend_svg to use them. images in svg appear to be working fine now,
and the origin = 'lower'|'upper' is respected.

Done.

This is actually a bug in the Python installer for Solaris as described
in this thread..
http://mail.python.org/pipermail/python-dev/2003-May/035560.html
I changed the following 2 defines in pyconfig.h
#define _XOPEN_SOURCE 500
#define _XOPEN_SOURCE_EXTENDED 0
and it passed that compile error.
ALSO, small bug in the matplotlib setupext.py, on line 531, the Numeric
install does not include the numarray_inc_dirs value to the include
list is is passing into the Extension object.
