Due the 16.16 format used by pixman to store floats, it can only render images with a maximum size of 32768 pixels (width or height). In bug #168964 we disabled the decoding of images larger than that cause that would break the rendering of the rest of the page, but we need to implement a way to render those images. We could replace NativeImagePtr with a tiled version of the image, with a new class or maybe reusing the TiledBackingStore.
