widgets: Fix out of bounds zoom in gradient editor 

When zooming using scroll events it is possible to zoom out of gradient
bounds because the check for out of bounds zoom happens with the zoom
value before the delta is applied. The correct way is to limit the zoom
value after the delta is applied.
