Thought: Could we avoid adding additional logistic through ImageResource (which
is oftentimes just an additional null-check) and instead do that in
LayoutImageResource (and other "hosts")? (I.e don't rely on the "fetch" layer
for anything but fetching the resource.) Just a thought thoug, no action need be
taken in/by this CL.

Sounds interesting and likely a good idea. Not sure how to keep track of the
idea. Create an issue or add a TODO?

Since it's a definite maybe, creating an issue might be more appropriate.

     enum SizeType {
         IntrinsicSize, // Report the intrinsic size.
         IntrinsicCorrectedToDPR, // Report the intrinsic size corrected to account for image density.
