Detailed Description

Manages the focus and z-ordering of ImageTags. Only one image tag may be selected at a time. Image tags show their 8 edit "handles" upon selection (see ImageTag class for more details) and get the highest z-ordering to make editing easier. This class is responsible for setting and dropping focus as the user navigates from tag to tag. The ImageTag is treated as a logical unit, however it's underlying representation consists of the physical rectangle and the 8 edit handles. JavaFX will report selection on the Node level (so either the Rectangle, or a singe edit handle), which makes keeping the entire image tag in focus a non-trivial problem.
