I've made a standalone example (enclosed). It simply makes a call to

GraphicsContext.DrawLines()

with and without clipping. In this case, it's actually a bit faster 
clipped (on OS-X). Maybe it's different with Paths -- I haven't dug into 
the MPL code to see how it's being used there.

Also, the whole thing almost hangs (134 seconds to draw) if I up the 
number of points to 5000!

Could you alter this to use the drawing calls MPL is actually using, 
then we can send it on the wxPython list.
