A Selection represents a portion of the data in a ``DataSource``, which
can be visually manipulated in a plot.
Selections are typically created by selecting points in a plot with
a ``SelectTool``, but can also be programmatically specified.

'''
When a data source is shared between multiple renderers, a row in the data
source will only be selected if that point for each renderer is selected. The
selection is made from the intersection of hit test results from all renderers.

'''
When a data source is shared between multiple renderers, selecting a point on
from any renderer will cause that row in the data source to be selected. The
selection is made from the union of hit test results from all renderers.
