I don't think that's true. The options only make sense for WebGL -- 
flipping which pixel is the first pixel, for example, doesn't do anything 
to 2D canvas, which works at a higher level.

(The other two options don't make much sense to me even for GL. If you 
don't want a color space, don't set one. If you don't want an alpha 
channel, don't set one. You control the image, after all.)

If options make sense for 2D canvas, then having ImageBitmap options would 
make sense, sure.
