We need to ensure that all image decoding happens in the well-sandboxed WebContent process, and not in the GPU process. Decoding bitmap images and images in fonts will be controlled by the ImageIO SPI: CGImageSourceSetAllowableTypes(). We will release assert if a PDF image is created in the GPU Process.
