Rectangle height and width

https://svgwg.org/svg2-draft/shapes.html#RectElement

"The width and height properties define the overall width and height of  
the rectangle. A negative value for either property is illegal and must be  
ignored as a parsing error."

Please please please fix this! There is absolutely no abstract  
justification for saying a rectangle cannot have a negative height (or  
width). It's just the same dimension in the other direction!

If you're interested in a very natural use case, please see
https://homepages.cwi.nl/~steven/xforms/histogram.html

(There are probably other places in the spec where negative values are  
unnecessarily restricted, but this is the one that I ran into in the above  
example).

Best wishes,
