@matplotlib/developers Can someone take a look at this today?

The fix looks correct to me and I can confirm that it resolves the issue.

Looking at that piece of code for the first time I don't understand how clip bool is supposed to work.
It assigns values to an array called val which is never used as far as I can see.
This is confirmed by trying to do cNorm2(120) which returns 1.20202020202 regardless of whether clip is True or False (with vmax=100). The solution should be to assign result rather than val but it would need a test too.

I don't think this is a new issue so I am fine with merging this as is and cutting 1.4.3 and postponing the clip issue to 1.4.x

@tacaswell I submitted a pr against your branch which I think should address the clip issue. If you think this is to high risk I am fine with merging this as is and postponing it to 1.4.x as I said above.

@jenshnielsen Looks good. If travis passes I will merge this PR.
