In bug 321054 comment 47 darin suggested implementing a stub imgIDecoderObserver implementation with all the methods empty so that the empty methods could be shared between the many implementations in content/layout.  This would be a lot like the existing nsStubDocumentObserver class.

patch

I couldn't touch nsImageLoadingContent and nsObjectLoadingContent because they inherit from interfaces that inherit from imgIDecoderObserver rather than inheriting directly.

This appears to have brought btek Tp down by about 2 ms. Yay! A bit hard to say for sure since it was followed by the patch for bug 339041 which brought it down an additional 4 or 5 ms.
