BorderLayout does not guarantee equal sizing of its children, so having
a component centered between two components of unequal sizes will leave
it centered relative to their sizes, such as the following:
```
|-----BorderLayout-------------------------------------------|
||----WEST----||------CENTER------||----------EAST----------||
||------------||------------------||------------------------||
|------------------------------------------------------------|
```
Conversely, GridLayout uses fixed, equal-width columns for its children,
ensuring the center component will always occupy the center third of the
parent's dimensions.
P.S. This change causes labels to truncate earlier as they do not expand
beyond a third of the parent container's dimensions. Because the use
case for this component is with small labels, I do not anticipate this
will cause breakage.
