How would that work for horizontal bar charts in which bars with no hits would be displayed the same as bars with a single hit?

I just attempted to draw a rectangle with dimensions 3@3 corner: 9@3. Nothing gets drawn. The reason that nothing is drawn is that the width of the rectangle is 0. This makes sense for real numbers but for a pixelated screen or other display medium the dimensions of the rectangle should be 1 x 7 not 0 x 6!?. This is 7 pixels needed to draw, not 0.
The same issues occur for the height of the rectangles.
I would think that the way things work would cause all kinds of problems but since Rectangles are pretty basic, either I am wrong, or every bit of Squeak code using rectangles has adjusted accordingly.
Please clarify.
How do Java and other languages handle this?
