Fix list parameters passed to artists

[has2k1]

Problem

When artists are being drawn, the geometries outside the viewport
are removed before the drawing. The parameters that correspond to
removed geometries are left unchanged and so they are ill-matched
with the remaining geometries.

Solution

Keep track of which geometries are removed, and remove the
corresponding elements in the parameter values.

Fixes #580

• Changed the hurricane katrina example to reflect the changes introduced in here.

One test failure.

The file header at lib/cartopy/mpl/feature_artist.py is out of date. The last commit was in 2017, but the copyright states it was 2016.

Can I update the date at the top of the affected file?

You should if you changed it.

Looks like you'll also need to sign the CLA as well.

[has2k1]

I signed the CLA form and emailed a copy to the address and it's been a while without a reply.

Ping @marqh, I think?

It would be great to have tests for all feature types, but it does not look easy. Any ideas on to generate good tests? For the ShapelyFeature the Katrina example now touches on code introduced in this PR (it is a "test" of sorts).

Rebased and travis did not like it. Maybe it now requires #926.

[dopplershift]

Yeah, #926 fixes a lot of testing issues. @pelson ?

This has been a really valuable PR that has ultimately led to #1019, which is my preferred direction for finer control of the style through add_geometries (and ```add_feature``).

As such, I don't think we need this PR open any further.
The relevant thread of conversation is #1019 (comment). As discussed there, there is the potential for an extension to create a GeometryCollection, but even that is probably best served in a new PR.

Thanks again for your input on this @has2k1 - it has been super useful, and I'm really pleased with the outcome, which I consider to be an extremely powerful interfaces for all sorts of purposed.
