Exclude image/text from Scene Erasing
Sometimes it's necessary to exclude an image/text from erasing.
It's possible to do this now, as following:
1. Copy scene.
2. Set all images/text of scene 1 to erase, except these you do not want to be erased.
3. On the new scene, delete all images/text except these you want to be repeated.
However, the above method is not that good, because the erasing starts right after the drawing of the last layer.
I need all layers to be visible for a couple of seconds after the last drawing, and after that I want to erase only some of these, and not all of them, so the next scene will have only these.
