* The {@code GeneralPath} class represents a geometric path

* <p>
* {@code GeneralPath} is a legacy final class which exactly
* implements the behavior of its superclass {@link Path2D.Float}.
* Together with {@link Path2D.Double}, the {@link Path2D} classes
* provide full implementations of a general geometric path that
* support all of the functionality of the {@link Shape} and
* {@link PathIterator} interfaces with the ability to explicitly
* select different levels of internal coordinate precision.
* <p>
* Use {@code Path2D.Float} (or this legacy {@code GeneralPath}
* subclass) when dealing with data that can be represented
* and used with floating point precision. Use {@code Path2D.Double}
* for data that requires the accuracy or range of double precision.
