I know Chrome sees memory pressure from the downsampling two-step on some pages, so I'd think this is could be useful for us, too. Isn't it going to require fairly large and intrusive changes to several different third-party libraries, though? Also, different ports use different image downscaling algorithms; I can think of ways to try to enable incremental downscaling callbacks so you don't have to implement N downscales in each of M decoders, but none that are both general and performant. I'd love to see a proposal on this. Tom (from the right account this time)
