Returns a LeadRectD resulting from inflating the specified rectangle by the specified amount.
rect
The rectangle to inflate.
width
The amount to inflate this rect horizontally.
height
The amount to inflate this rect vertically.
The inflation along an axis is in two directions (negative direction and positive direction). For example, if a 150 by 150 rectangle is inflated by 50 in the x-axis, the resulting rectangle will be 250 units long (the original 150, the 50 in the negative direction, and the 50 in the positive direction) maintaining the rectangle's geometric center. If either width or height is negative, the rectangle is deflated in the corresponding direction.
