matplotlib Code

Experimental clipping of Line _transformed_path to speed zoom and pan.

This can be modified to work with x monotonically decreasing, but
for a first try it works only with x monotonically increasing.
The intention is to greatly speed up zooming and panning into
a small segment of a very long time series (e.g., 10^6 points)
without incurring any significant speed penalty in other situations.

fixed a few bugs introduced in r7098(aspect for log-log plot).

aspect for log-log plot

clabel takes new kwarg, rightside_up (defaults to True)

Move from LABELPAD class attribute on an Axis to a labelpad instance attribute. Add a label argument to Axes.set_[xy]label to control the spacing between a label and its axis.

Clean up multiprocess a little. Remove unused import, ensure Gtk backend is used, and replace pylab with pyplot.

remove reserved word as from example
