- Very large image support (e.g. pathology > 4kx4k resolution)
- Performance related
- switch to lower resolution image during ww/wc operation to improve framerate
- only regenerate the part of the rendered image that is actually visible - perhaps by tiling it
- Create a CustomElement for cornerstone images http://www.html5rocks.com/en/tutorials/webcomponents/customelements/
- Sharing of LUT's between multiple viewports for linked ww/wc use case
