Feature request : snapping oval or rectangular gradient angle

[pierrelabreche]

To rotate the oval or rectangle, drag the line that connects the center to the outermost oval or rectangle.

Would it possible to make angle adjustment snapping 15 degree steps, like the compass control

To set an angle, click anywhere inside the control and drag to set the pointer -- if you hold down the shift key while dragging, the angle snaps to the nearest multiple of 15 degrees
