Change savefig.dpi and figure.dpi defaults

[jmehne]

Change the default values for savefig.dpi and figure.dpi as suggested in #305.

savefig.dpi: 100 -> 'figure'
figure.dpi: 80 -> 100

👍 from me

Cherry-picked to v2.0.x as a903315. @tacaswell, did I do that correctly?

[mdboom]

@efiring: We've been cherry-picking the merge commit (which in this case is 6333526) rather than the individual commits (in this case 016406a). I think you did the latter. It's not a huge difference, but it does keep a mention in the logs of which PR a feature came from for later reference if you do the former. It's also easier to merge a multi-commit PR that way.

@mdboom, OK, that makes sense, thank you. That requires using the "-m parent" option to the "git cherry-pick" command, doesn't it? How does one know the parent number?

[tacaswell]

It is always parent 1 because we are meeting things into master

Travis is complaining about the original commit, but it seems unrelated to the actual file changes. Should I be worried?

Something seems to have gone wrong with that file, #5652 had the same issue.

[jmehne]

Hm, strange. It seems like only AppVeyor was run.
