Landing changes Vidur made while the tree was closed for beta1 work, here's a list of the changes. r=me [1] Cutting down the size of content. Made nsIJSScriptObject inherit from nsIScriptObjectOwner [2] Cutting down the size of content. Made nsITextContent inherit from nsIContent. [3] Cutting down the size of content. Moved implementation of nsIDOMReceiver to nsListenerManager. This is not true aggregation since it isn't transitive, but it's OK for now. It will be necessary for nsListenerManager to have a reference to its content in the future anyway, so the transitivity could be done. dom/public/nsDOMPropEnums.h,v - bug 12559 dom/public/nsIJSScriptObject.h,v -

Landing changes Vidur made while the tree was closed for beta1 work, here's a list of the changes. r=me [1] Cutting down the size of content. Made nsIJSScriptObject inherit from nsIScriptObjectOwner [2] Cutting down the size of content. Made nsITextContent inherit from nsIContent. [3] Cutting down the size of content. Moved implementation of nsIDOMReceiver to nsListenerManager. This is not true aggregation since it isn't transitive, but it's OK for now. It will be necessary for nsListenerManager to have a reference to its content in the future anyway, so the transitivity could be done. dom/public/nsDOMPropEnums.h,v - bug 12559 dom/public/nsIJSScriptObject.h,v -

Moved implementation of nsIDOMReceiver to nsListenerManager. This is not true aggregation since it isn't transitive, but it's OK for now. It will be necessary for nsListenerManager to have a reference to its content in the future anyway, so the transitivity could be done. dom/public/nsDOMPropEnums.h,v - bug 12559 dom/public/nsIJSScriptObject.h,v -

Landing changes Vidur made while the tree was closed for beta1 work, here's a list of the changes. r=me [1] Cutting down the size of content. Made nsIJSScriptObject inherit from nsIScriptObjectOwner [2] Cutting down the size of content. Made nsITextContent inherit from nsIContent. [3] Cutting down the size of content. Moved implementation of nsIDOMReceiver to nsListenerManager. This is not true aggregation since it isn't transitive, but it's OK for now. It will be necessary for nsListenerManager to have a reference to its content in the future anyway, so the transitivity could be done. dom/public/nsDOMPropEnums.h,v - bug 12559 dom/public/nsIJSScriptObject.h,v -
