Fixes #1625

[sankhesh]

@chaosphere2112 This branch is ready to be merged.

I can remove the code duplication in a separate branch once #1678 is merged. Lets not hold this back.

@sankhesh this branch needs to be updated as it has merge conflict..

[doutriaux1]

@sankhesh I would like to merge this branch AFTER the colormaps one, as I think it will be easier to merge potential breakage that way.

[sankhesh]

@doutriaux1 This branch is ready for merge.

The failures are because I did not merge your colormaps baselines with this branch's baselines. If you like I can do that and re-trigger these builds.

[sankhesh]

Please make sure to merge #1693 before merging this branch.

[sankhesh]

Re-triggered builds with new baselines.

[doutriaux1]

Rh full issues are xfvb related. I probably need to restart it. Rh mesa passes. Will wait for a Mac and merge in

[doutriaux1]

@sankesh will update thrshold on your test failing on Ubuntu 15.10 before merging in if macs come out ok

[aashish24]

@doutriaux1 so this would be our last PR for now?

[doutriaux1]

@aashish24 yes, but stipple test fails. What do you prefer try with a new baseline? Or increase threshold and merge?

[aashish24]

@doutriaux1 I looked at the differences and to me it seems to be system specific changes and not that the code is buggy. I would suggest increase the threshold and merge.

[aashish24]

@sankhesh can you increase the threshold?

[chaosphere2112]

@sankhesh @aashish24 Yeah, I had to up the threshold for my stipple test.

[sankhesh]

Done.

[aashish24]

thanks @sankhesh
