renderPseudoColorImage: This renders a grayscale image as a color image using a color lookup table after first applying the modality and VOI LUT transformations. This is the described approach for pseudo-color image display in the DICOM standard (http://dicom.nema.org/medical/dicom/current/output/chtml/part04/sect_N.2.html).

Previously, users had to use convertToFalseColorImage which converted the entire grayscale image to a color image, and then rendered the RGB pixels. Now, you can set the 'colormap' property on the viewport and the image will be displayed in false color. The False Color Mapping and Composite Images examples have been updated accordingly.

renderLabelMapImage: In medical imaging it is very common to have results stored as label maps. Pixel values are set to arbitrary numbers which represent something specific in an image (e.g. 1 for heart, 2 for lung). These label maps do not require any modality LUT or VOI LUT transformations and can just be mapped to RGBA pixels through color lookup tables. Support for label maps has now (finally!) been added to Cornerstone. Just set the viewport property 'labelmap' to true and add a colormap and you can display a label map.
renderGrayscaleImage: Now has support for rendering using either just the alpha channel or RGBA channels. This is required for proper layer support.
Removed redundant code in renderWebImage which was being run before renderColorImage was being called. This should hopefully fix performance issues for Web images that have been reported (#164).

Version 1.0.0

Updated to 1.0.0 because 0.13.1 introduced a breaking change with jQuery injection. This doesn't break usage if you are using HTML script tags, but if you are using Cornerstone in a module system, Cornerstone may not properly find jQuery.

The solution for this is to inject your jQuery instance into Cornerstone as follows:

cornerstone.external.$ = $;

An example commit doing this in the OHIF Viewer Meteor application is here: https://github.com/OHIF/Viewers/commit/012bba44806d0fb9bb60af329c4875e7f6b751e0#diff-d9ccd906dfc48b4589d720766fe14715R25

We apologize for any headaches that the breaking change 0.13.1 may have caused for those using module systems.

Version 0.13.2 (deprecated due to breaking change)

Added native CustomEvents that are triggered parallel to the jQuery events. This is part of a transition to drop the jQuery dependency entirely.
Added the EventTarget interface to cornerstone.events. You can now use cornerstone.events.addEventListener to listen to events. The parallel events have the same names as the current events, but are all lower case.

e.g. CornerstoneImageRendered has a native CustomEvent name 'cornerstoneimagerendered'
