The list of things that make up state seems a little short. You should at least make it clear that there is another dozen tiny settings involved. And you should mention the extra draw calls that filters cause.
The section about avoiding duplicate data for context loss seems to be overly enthusiastic about loading from an URL. You should account for the local caching of the http resource that is sure to happen. Also, do make the distinction between compressed and decoded bitmaps clearer. Not even embedded bitmaps are kept around decoded by the runtime all the time.
The sections that praises texture compression should have a nod to the fact that Flash/AIR can compress to a gpu supported format at runtime. On some platforms.
The section on performance could use a note about the weird interactions between stage2d and stage3d content on subpar profiles.
