Regression in maximum path size #4407
Description
With matplotlib 1.4.3 it is possible to draw at least a random time series of 70,000 points on the Qt4Agg backend:
$ python -c 'import numpy as np; from matplotlib import pyplot as plt; plt.plot(np.random.rand(70000)); plt.show()'
With the current HEAD, an OverflowError is thrown:
OverflowError: In draw_path: Exceeded cell block limit
Perhaps it's just a transient regression, but I didn't see it mentioned anywhere.

This sounds very familiar, but I could have sworn it was something to do
with the macosx backend and old limitations of quartz.

It seems odd that 1.4.3 and master are behaving differently; I think that with path simplification, both should be able to handle the test case.

Do you have any rcParams in effect (in your matplotlibrc for example)?

This may have to do with "upgrading" to Agg-svn from Agg-2.4.

I thought both would pick up the same matplotlibrc anyways but just to be sure I removed it, and see the same difference.

See #4408.
