## Discussion

When presented as part of the requested operations to the function [`CGWaitForScreenUpdateRects(_:_:_:_:_:)`](/documentation/CoreGraphics/CGWaitForScreenUpdateRects(_:_:_:_:_:)), specifies that the function should try to minimize the number of rectangles returned to represent the changed areas of the display.  The function may combine adjacent rectangles within a larger bounding rectangle, which may include unmodified areas of the display.
