I would like to set an individual pixel in Slick (i.e

Graphics g = img.getGraphics(); g.setColor(color); g.fillRect(x,y,1,1); g.flush();//IMPORTANT!!!
I just tried this out myself, which is how I discovered the importance of the flush call. Also check out the example ImageGraphcisTest.java in the Slick2D src folder.
