optimizing drawing to drawing_area

[Rok Roskar <rroskar artsci wustl edu>]

I am drawing a large array of data (1024x1024) to a drawing_area and it 
seems to be really slow. Is there any way to optimize it? I first read the 
data into an array and then create the pixmap pixel by pixel... then I 
draw the entire pixmap to the drawing area at once. Any ideas?
