+2007-11-09 Applied Martin Teichmann's patch 1828813: a QPainter is used in
+ paintEvent, which has to be destroyed using the method end(). If
+ matplotlib raises an exception before the call to end - and it
+ does if you feed it with bad data - this method end() is never
+ called and Qt4 will start spitting error messages - DSD
+
2007-11-09 Moved pyparsing back into matplotlib namespace. Don't use
system pyparsing, API is too variable from one release
to the next - DSD
