In the Whiteboard:

If you are using the Line tool and draw a 1-pixel width vertical line where the start and end points have the same X coordinate (different Y coordinates), the line disappears.

The same occurs with horizontal lines.

Victor, it's probably a miscalculation in the ascent/descent calculation. You may need to add a special case exception to the code to handle vertical/horizontal lines with no change in the x or y coordinates respectively.


Also, when is the source code for see more the Ray modules supposed to be released?
