I am building a display window for live sonar data and wan't to
create a scrolling display with the sonar data moving upwards
as I paint new data on the bottom of the window. I am currently
using XCopyArea to perform the scroll and XPutImage to draw a new
line of 8 bit grayscale data on the bottom of the window.  

Is there a faster way to do this ????

Thanks,
Stuart
