If you use blend to draw an image it stretches slightly down and to the right even if the
source and dest rectangles match the image exactly. It looks like it gets stretched by one
pixel.

This is in Processing v1.1 on OSX 10.6.

Here is a simple demo. Notice that this image drifts diagonally when it shouldn't.

import processing.video.*;
Capture cam;

void setup() {
size(640,480);
cam = new Capture(this, width, height);
}

void draw() {
PImage previousFrame = get();
cam.read();
image(cam, 0, 0, width, height);
blend(previousFrame, 0, 0, width, height, 0,0, width, height, LIGHTEST);
}
