clip_on was a suggested way of getting around the clipping that happens 
at the edge of a frame.  In the Sage project, we are always setting the 
limits on the axes via set_xlim and set_ylim.  Is there any way to get 
the lines and circles that pass across the edge of the usual clip 
boundary to still be drawn, even if we have set the xlim and ylim of the 
axis?

Basically (using an example from the gallery), is there a way to get the 
scatter plot circles below not clipped, while still having the y-axis 
only go from -2 to 2?  If not, is there a way to easily calculate the 
protrusion of the various objects, like the circles below, so we know 
how much to adjust the axes to just include the circles?

import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
x = np.linspace(0r,2*np.pi,100r)
y = 2*np.sin(x)
ax = fig.add_subplot(1,1,1)
q=ax.scatter(x,y)
ax.set_ylim([-2,2])
q.set_clip_on(False)
ax.set_clip_on(False)
ax.spines['left'].set_position(('outward',10))
ax.spines['bottom'].set_position(('outward',10))
ax.spines['top'].set_color('none')
ax.spines['right'].set_color('none')
ax.xaxis.set_ticks_position('bottom')
ax.yaxis.set_ticks_position('left')
fig.savefig('test.png')

Thanks,

Jason
