[SPRINT] Much better alpha control in mplot3d. Closes #1541 by WeatherGod · Pull Request #2169 · matplotlib/matplotlib

@WeatherGod

Probably haven't solved them all, but this gets most of them.

Edit: Damon here. I edited the title of this to contain the word 'sprint'.

@WeatherGod

Again, errors appear to be either the new weirdness with loader or some other error with fonts unrelated to my work.

@mdboom

We should probably add a test for this.

@dmcdougall

+1 for the test. After that I think it's good to go. I don't think it has to be an image test.

@pelson

@WeatherGod - do you mind rebasing, and we can merge this. I don't know if we have any tests for mplot3d yet, so I'm prepared to merge without a test at this point.

@WeatherGod

Uhm, I am having a vague recollection that I encountered some issues with
this particular fix. Until I can verify or not, please don't merge.

@pelson

Ok. Closing until its ready.
