Concerns around impl From<((f64, f64), (f64, f64))> for Rect

[cmyr]

This is currently implemented, and I think that it is likely to be misused.

A rect can be constructed from a pair of points or from a point and a size. There is no way to know from this implementation which behaviour to expect.

I think it would be reasonable to have a conversion between Rect and (f64, f64, f64, f64), cooresponding to (minx, miny, maxx, maxy), but I think ((f64, f64), (f64, f64)), if implemented, should default to (origin, size), but the fact that there's any room for confusion makes me feel that it should be removed.

Totally fine with me to remove this.

unfortunately it's a breaking change..

Move fast and break things, that's my current motto. Although we can think of a few things to batch up here, possibly another shot at #4 if that breaks anything.
