APIs are not theoretical math: they are useful tools to create content. Allowing sizes to be negative has many use cases for artists without always an easy workaround (due to interpolation, timing, etc.). Many (most?) 2D API framworks allow rectangle sizes to be negative. There are no downsides that I know of not allowing it, and it's generally trivial to implement.

There are fatal problems which Amelia and I have pointed out which
make this currently impossible without changing other aspects of how
we're designing the platform.  "Just make it to go the other way" is
the obvious interpretation of a negative width, yes, but *specifying*
a negative width has severe issues in current SVG.
