## scroll-box

Arguments: window box offset

Scrolls (in the sense described below) the contents of box on window by offset (which is a position, see make-position, whose x and y components say how far to scroll in the x and y directions). Pixels moved out of box are lost. Background texture is moved into box to replace pixels that have moved. box must be a box, see make-box.

This function does not do a true scroll. It simply copies a rectangular portion of the window's contents to another place in the window, and is therefore like a special case of copy-stream-area.

### GTK Note

This function has not yet been implemented on the GTK platform. Calling the function on GTK will simply invoke the `*gtk-compatibility-warning-action*`.
