= Analysis =

== Overview ==
There is a palette that makes preview of a resource. An extension point is needed because the palette should be able to display different kinds of resources - audio, video, image and so on.

== Task requirements ==
 * Create an extension point for resource preview display.
 * The interface (for the extension point) should have a preview method that returns !VisualElement.
 * The palette should be able to display this !VisualElement.

== Task result ==
 * The result of this task should be source code.

== Implementation idea ==
 * Add an extension point to the base.model.resource module.
 * Create an interface (for the extension point) that has a method preview that returns !VisualElement.

== How to demo ==
 * Run Sophie 2.0
 * Select a video resource from one of the palettes with resources.
 * The resource should be previewed in the appropriate palette.
 * Select an image resource.
 * The resource should be previewed in the same palette.
