Implement a "disabled" state

[GoogleCodeExporter]

Please explain how the new feature would appear to an end-user:

A disabled checkbox should support having a different look and style that can 
be defined via CSS 
by the developer.

As a bonus, perhaps the end user is greeted with a dialog or other feedback for 
attempting to use 
a disabled control.

Please explain how the feature should be implemented in the JS source:
This requires:
1. A new optional style and the appropriate settings. This MUST be optional and 
should have 
some default that leverages the existing settings (perhaps an opacity change to 
denote "disabled" 
or something similar.
2. Code to support detection and use of a "disabled" state.
3. A set of defaults that get overridden by the developer when they choose to 
implement the 
state themselves.

If you have a code sample for the feature or have a diff of it being
implemented, please include it:

Not sure if this is already implemented or not, but you could simply change the 
CSS opacity of the element rather than use a new "disabled" image or something.
