An area represents a segment of a preview screen and has a coordinate for
the top-left corner of the screen and a width and height. This implies that
areas are always rectangular. Moreover, these coordinates are given as
fractions of the total screen size, i.e. they will be in the range [0, 1].
An area also has a key region, which associates it to a logical region by
means of an ID. The associated region gives the area a name and a colour.
The reason for this is that a region can exist on multiple screens and can
have different sizes but still must contain the same media items.
