[cssom-view] DOMRect with aliases x, y to left, top?

Hi,

Would it be possible to add alias attributes 'x' and 'y' that point to 'left' and 'top'? That would make it more compatible with SVGRect and the SVG WG could start replacing SVGRect[1] with DOMRect as well for a unified platform.

Greetings,
Dirk
