Igor Zinken 712c7abd71 Add layer preview thumbnails to layers panel (#84) ...

### Motivation

It'd be great if we could see a small thumbnail preview in the layers panel to more easily distinguish between layers visually.

In this changeset we introduce the thumbnail cache. When enabled, each layer is represented by a thumbnail which can be requested from multiple subscribed consumers (currently only the layer panel).

Thumbnail updates are deferred to keep CPU usage low and performance high.
