[CREATE] OpenRaster as multi-resolution format

[Frédéric]

Hello,

I'm making panoramas, and the software I'm using (not free :o/ ) is able to 
use images at different resolutions (maybe hugin can do that...). But in 
fact, it just convert low-res images to fit the larger-res ones. The 
result is a big image with some areas in full res, and some in low res, 
but upscaled. So, this is a wast of place.

I was wondering if there are images formats able to store an image with 
different resolution to deal with this problem? As you are working on a 
new open-format for images, could this feature be added to it? Reading the 
spec, I was thinking that it could be done using different layers, and 
layer masks. The low-res layer could just be upscaled when displayed... 
But I'm far from an expert :o/
