This makes sense if you consider the pixel "at" (0,0) to actually occupy a 1x1 rectangle, extending from (0,0) to (1,1). So the point (0.7, 0.7) should actually be considered to be within the pixel at (0,0). Distances, on the other hand, such as the radius of circles, should be rounded. Just my opinion. -Christopher
