Jesse Bounds dfd40b27a5 [tests] Add tests for shape overlays crossing the antimeridian
This adds two tests:

AntimeridianAnnotationSmall: Test that a shape that is represented with
+-180 longitudinal values is drawn spanning the antimeridian. In other
words, it is rendered as a "small" shape as opposed to one that spans
around the world to reach the other side of the antimeridian. This test
is currently failing at the time of this commit.

AntimeridianAnnotationLarge: Test that a shape that is represented with
points that do not cross the +-180 boundary is rendered as a "large"
shape. In other words, it is rendered by wrapping around the world to
reach the other side of the meridian. This test is currently passing at
the time of this commit.
