multiple gradients:

Few multi-gradients concept rules:

1. the gradient that is painted first shows first.the next one will be painted below it.
2. when painting complex yet beautiful gradients i can paint the first gradient as if it is the only one i want to.then paint the second one that will be shown below the first one also as if it is the only one i want to and so on...
3. defining (transparent) color-stops in a gradient will give transparency for the gradient for that area so that other gradients below it will be visibile.
