      GRect

The GRect class is a graphical object whose appearance consists of a rectangular box.

Constructor Summary
`GRect(x, y)` Constructs a new rectangle with the specified width and height, positioned at the origin.
`GRect(x, y, width, height)` Constructs a new rectangle with the specified bounds.

Method Summary
`setBounds(x, y, width, height)` Changes the bounds of this object to the specified values.
`setSize(width, height)` Changes the size of this object to the specified width and height.

Inherited Method Summary
`contains(x, y)` Checks to see whether a point is inside the object.
`getBounds()` Returns the bounding box for this object.
`getColor()` Returns the color used to display this object.
`getFillColor()` Returns the color used to display the filled region of this object.
`getHeight()` Returns the height of this object, which is defined to be the height of the bounding box.

`getX()` Returns the x-coordinate of the object.
`getY()` Returns the y-coordinate of the object.
`isVisible()` Checks to see whether this object is visible.
`isFilled()` Returns whether this object is filled.
`move(dx, dy)` Moves the object on the screen using the displacements `dx` and `dy`.
`movePolar(r, theta)` Moves the object using displacements given in polar coordinates.
~~`scale(sf)`~~ Scales the object on the screen by the scale factor `sf`, which applies in both dimensions.
`sendBackward()` Moves this object one step toward the back in the z dimension.
`sendForward()` Moves this object one step toward the front in the z dimension.
`sendToBack()` Moves this object to the back of the display in the z dimension.
`sendToFront()` Moves this object to the front of the display in the z dimension.
