matplotlib Code

Allow for numpy 1.04, which does not have ma.masked_invalid

Use our own "round" function, since it doesn't appear to exist in VS2003

Update dataLim only if some valid data are available.
This change means that plot([nan]) will generate an
empty plot instead of raising an obscure exception.

Restore ability of backend_driver.py to drive cairo.svg, etc.
