Find a way to synchronize canvas overlay with layers

[mateuszmigas]

Describe the bug The canvas overlay is not synchronized with the layers. Sometimes, the browser might render one before the other, resulting in "blinking" artifacts when selecting an area.

To Reproduce Steps to reproduce the behavior:

1. Draw something
2. Select "Rectangle Select" tool
3. Select some area
4. Press Escape, repeat until you notice blinking

Expected behavior There should be no blinking, obviously.

I added a fade-out animation to shapes and images to address this problem.
