Bug 1368776 - Part 9. Expose getting an image container at a given size. r=tnikkel This adds IsImageContainerAvailableAtSize and GetImageContainerAtSize to the imgIContainer interface, as well as stubbing it for all of the classes which implement it. The real implementations will follow for the more complicated classes (RasterImage, VectorImage).
