------- Additional Comments from Jens Alfke <snej at chromium.org>
This patch brings the settings of effectAllowed and dropEffect into compliance
with the HTML5 spec.
Includes a test case that checks the values of both properties on entry to
every standard drag-and-drop event, including the negotiation of a final
dropEffect from the source's and destination's requirements.
