Pick a point in 3D Viewer, view a 3D cursor

Medical Image Viewer, 3D Viewer

Overview

Currently, the user cannot ctrl+click on a point in the 3D Viewer (except to select a part of a Mesh), and the currently selected point is not visible in the 3D View.

• The users would like to be able to click on an ImageComponent to set the coordinates of a point, like when using Ctrl+Click on 2D Views.
• This should also work on a MeshComponent.
• Showing the position of this point as a 3D cursor (such as a 3D cross) would be a plus.
• Clicking on an Actor could also be used to select components (e.g. clicking on a mesh should select the associated mesh component)
