Adding Layers

[Gunes315]

As an artist I want to be able to layer different colors and parts of drawings to be able to look at them individually or mix colors as needed

• [ ] Button to add layers
• [ ] Different buttons to switch between which layer is currently worked on
• [ ] Up to 5 (?) layers have to be possible
• [ ] It has to be possible to choose, which layers are displayed and which are hidden
• [ ] It has to be possible to delete single layers, while leaving the rest intact
