void InflateRect( int x, int y );
void InflateRect( SIZE size );
x
Specifies the amount to increase or decrease CRect's width. It must be negative to decrease the width.
y
Specifies the amount to increase or decrease CRect's height. It must be negative to decrease the height.
size
Contains a SIZE or CSize that specifies x and y amounts to add to the CRect's height and width.
InflateRect's parameters are signed values; positive values inflate the CRect, and negative values deflate it.
When inflated, CRect's width is increased by two times x, and its height is increased by two times y.
