[GeometryInterface] add fromRect function in DOMQuad.

The fromRect(other) static method on DOMQuad
must create a DOMQuad from the DOMRectInit dictionary other.
To create a DOMQuad from a DOMRectInit dictionary other,
follow these steps:
1.Let x, y, width and height be the value of other’s x, y,
 width and height attributes, respectively.
2.Let point 1 be a new DOMPoint object with x set to x,
 y set to y, z set to zero and w set to one.
3.Let point 2 be a new DOMPoint object with x set to x + width,
 y set to y, z set to zero and w set to one.
4.Let point 3 be a new DOMPoint object with x set to x + width,
 y set to y + height, z set to zero and w set to one.
5.Let point 4 be a new DOMPoint object with x set to x,
 y set to y + height, z set to zero and w set to one.
6.Return a new DOMQuad with p1 set to point 1, p2 set to point 2,
 p3 set to point 3 and p4 set to point 4.

[GeometryInterface] add getBounds function in DOMQaud.

The getBounds() method, when invoked,
must run the following algorithm:
1.Let bounds be a DOMRect object.
2.Let left be the minimum of p1.x, p2.x, p3.x and p4.x.
3.Let top be the minimum of p1.y, p2.y, p3.y and p4.y.
4.Let right be the maximum of p1.x, p2.x, p3.x and p4.x.
5.Let bottom be the maximum of p1.y, p2.y, p3.y and p4.y.
6.Let x coordinate of bounds be left,
 y coordinate of bounds be top,
 width dimension of bounds be right - left
 and height dimension of bounds be bottom - top.
7.Return bounds.

Hwanseung, please update this issue.
I think you should update 'Exposed=' in WebIDL.
