The terminal copies the contents (characters and attributes) of all the cells in the rectangle from
rightcolumn (both inclusive) to a rectangle of the same size at the location
destinationleftcolumn. Overlapping rectangles for source and destination are supported.
All multi column cells that intersect the destination rectangle will be cleared without changing their background color. If the source rectangle has multi column cells that are only partially inside the source rectangle the copy will have cleared cells with the same background color in their place.
When only some of the lines have set set double width line, the region this sequence acts upon might not look rectangular in to the user on display.
