UbuntuShape should support "mounts"

[Michał Sawicz]

When an image is of different aspect ratio than the UbuntuShape, it should be possible to provide a "mount" - a background image that will be drawn behind the image itself.

This could be done by using the UbuntuShape with just the mount image and overlaying a cropped image on top of the UbuntuShape, but building it into the UbuntuShape should be more performant and we'd need to wrap the UbuntuShape as a QML component otherwise.

I propose the following addition to the UbuntuShape API:

UbuntuShape {
  property Image mount: undefined
}

So, what you want is something like this, but inside an UbuntuShape?

Item {
  id: shape

  Image {
     id: mount
     anchors.fill: shape
     source: "mountSource.png"
  }

  Image {
    id: crop
    anchors {
       top: parent.top
       bottom: parent.bottom
    }
    // crop.width < shape.width
    source: "cropSource.png"
  }
}

What you propose that you could put the crop image on top of the UbuntuShape does not work if (as in the example) the cropped image still touches at least one of the edges of the UbuntuShape, because the shadow/shape of the UbuntuShape will not be applied to the cropped image there.

what is the use case? (example)

Indeed.

The Video lens is supposed to display horizontal videos (taken with the
phone camera / from the interwebs) in such a mount inside a vertical
tile to maintain consistency.
