          Issue Type: Feature Request
      Security Level: Public (Everyone can see)

According to Yahoo performance recommendations ([1], see "Post-load Components"),

visual components should be loaded on page load ({{onload}} event)
to avoid heavy JavaScript processing before page is completely visually built.

In RichFaces, it is simple task using {{JavaScriptService}}, which enables you to collect and inject JavaScript snippets which should be loaded using jQuery {{$(document).ready(...)}}.

Thanks to CDK templates, it's also simple change in renderers, just move component contructor to newly created CDK tag {{<cdk:onloadScript>}}, which would delegate to {{JavaScriptService}} (if {{JavaScriptService}} not found, processing may fall back to rendering {{<script>window.addEventHandler('load', ...)</script>}}, but this is optional part.
