I'm not sure they were ever used by Android. Certainly not in a long time.

That said, I *do* want to give Android a facility to do something like this in
the new image decoders. They want a callback to choose the size, and we'll give
them the image that is closest to that size. (See
https://docs.google.com/document/d/1c4tisA2soRYGX9u-rmI5uDk4srK0MSjvxky4rsDb9...
for more info.)

Do you want to unlegacy this API as is, or land this and create a new extension
when you invent it?

I'm going to use an entirely new set of decoders. So no need to keep this API.

lgtm

Sorry, I saw all that green from the try results, and I thought there had
already been an lgtm...

The code may be informative for the new implementation, but it will still be in
the history.
