struct Window * win WORD dx WORD dy WORD xmin WORD ymin WORD xmax WORD ymax
FUNCTION
Scrolls the content of the rectangle defined by (xmin,ymin)- (xmax,ymax) by (dx,dy) towards (0,0). This function calls ScrollRasterBF(). The advantage of this function over calling ScrollRasterBF() is that the window will be informed about damages. A damage happens if in a simple window parts from concelealed areas are scrolled to visible areas. The visible areas will be blank as simple windows store no data for concealed areas. The blank parts that appear due to the scroll will be filled with EraseRect() and are not considered damaged areas.
