The CropField component is a vaadin Field that shows a single image and overlays it with capabilities to select, transform and move a cropping area within it.
Basically, it is a jCrop clone for Vaadin/GWT.
Features include:
* adding handlers to be notified when selection changes
* setting min/max size of the selection
* forcing an aspect ratio on the selection
* selecting in the true size coordinate system of scaled images
