Issue description

When you have a Sprite node with self-modulate enabled on it and set it up to clip its children, then the transparency of the self-modulate is applied to the children.

In the video you can see how I set the parent's self modulate to red and reduce its alpha. Once I enable the clipping, the reduced alpha is also applied to the child nodes, but I think it should not as self-modulate should not affect child nodes.

Steps to reproduce

1. Create two sprites, make one the child of the other.
2. Change the self-modulate of the parent to some translucent color.
3. Change the clip-children setting of the parent to "clip + draw"
