Summary [CG] Support frameHasAlphaAtIndex for image types other than JPEG

We only return false form frameHasAlphaAtIndex() for JPEG images. PNG and GIF images are treated as having alpha even when they do not. frameHasAlphaAtIndex() will be the basis for various painting optimizations, so it would be good to fix this.
