The colorbar returns a Colorbar object, the "solids" attribute of which 
is a Quadmesh; so you should be able to execute

cbar.solids.set_antialiased(False)

to turn off antialiasing.  With a bit of testing, however, I am not 
seeing any difference, so I'm not sure what is going on, and I don't 
have time now to investigate.
