[dash] Should support previews of different height.

[Alejandro J. Cura]

When the scope does not specify a picture for the preview, the outline of the Ubuntu shape should not be shown.
Attached is a screenshot that shows this error.

Visual design for "small" previews:

Marking this as fix released as problem is outdated now that previews are full screen

As far as I can tell, design does not allow previews with no images - and even if, it doesn't look like in the image now.

I can see it when I get a login error when trying to install an application, and when doing a long press on an app.

Marking the UX task as invalid, because this document shows the preview without an image:

I would actually like input on the transitions from ubuntu-ux.

Problem is we can't predict what size a preview will be, because we don't know what type of a preview it's going to be. This is especially tricky with swiping between previews (not yet released), where you might swipe between differently sized previews (even if that's not the general case - it might be an error one where the previews in the current category are tall, but network decided to go away and you get an error preview which is small).

Our current plan was to open the whole dash for preview as soon as you tap an item other than an installed app - but if we want to support "smaller" previews, it's going to be weird if we open the whole dash just to shrink back again to the preview. So I'm asking for some guidance on what to do here - should we put a spinner on top of the whole dash while waiting for the preview and open it with the target size straight away? What if an image that arrives asynchronously is higher than the default height for that kind of preview - should we open the dash more? What of switching between previews - should we switch at current size and expand / contract when necessary?

How do you swipe between previews when one preview has multiple
images? (that is, multiple screenshots in the app preview)

You just swipe not-on-images, same as with carousel and the dash.
