### GreSetViewingLimits - Remarks

This function sets the boundaries of the viewing (clip) limits in model space to the specified values. The boundaries are inclusive and are not clipped. The viewing-limit coordinates are transformed to make a clipping rectangle in page-coordinate or device-coordinate space. Any rotation or shear of this rectangle is ignored. When the left boundary is greater than the right, or the bottom boundary is greater than the top, a NULL rectangle is defined and all points are clipped.
