BREAKING CHANGE
The current coordinate configuration of a rect annotation seems inverted. From the rect annotation PR: #180 I'm proposing to invert the x0 and x1 meaning on the annotation coordinate.
With x0 I always think of the left hand side of a rectangle, and with x1 the right hand side.
So with that in mind I'd like to change that with

x0	x1	y0	y1	render implications
undefined	undefined	undefined	undefined	no rendered annotation
defined	undefined (coerced to x domain end)	undefined (coerced to y domain end)	undefined (coerced to y domain start)	rect will be drawn from x0 to xDomain end with full chart height
undefined (coerced to x domain start)	defined	undefined (coerced to y domain end)	undefined (coerced to y domain start)	rect will be drawn from x domain start to x1 with full chart height
undefined (coerced to x domain start)	undefined (coerced to x domain end)	defined	undefined (coerced to y domain start)	rect will be drawn from y domain start to y0 with full chart width
undefined (coerced to x domain start)	undefined (coerced to x domain end)	undefined (coerced to y domain end)	defined	rect will be drawn from y1 to y domain end with full chart width

@nickofthyme do you think we should to the same also for the y0 and y1 values?

Tested locally, LGTM.

Ya both seem to be inverted. I think swapping y0 and y1 would be good to stay consistent.
