Details

This is a metabug for adding downscale-during-decode support for all important image decoders. At a minimum, we should support it for JPEG, PNG, and GIF.

I'm hoping someone will someday implement a WebVR viewer capable of displaying high resolution (1000+ megapixel) equirectangular panoramic jpg images, which loads the source image into a hidden offscreen buffer and samples and scales appropriate sections of that buffer from it's full native resolution to a size suitable for output to the display, based on current view direction and zoom level. I would hope Firefox decoding doesn't preclude such software from ever being implemented.
This is only about downscaling images when a webpage requests an image to be drawn at a smaller size then the image is. So if content doesn't ask for it, downscaling won't happen.
