As other widgets may be interested in the image info, this should be part of the DM node, which the media edit dialog then fetches and uses to populate the MediaSizeWidget. Other fixes: * Remove spinner, not really necessary as the orignal size button is disabled if the orignal dimensions aren't set. * Don't wait until image info call to resolve to initialise size widget values. These should always be available instantly from the attributes. Depends on I9530ed4257e88b in core. Change-Id: I394f49941b621059bc08c8a8f79471b2fe16c7d8
