Commit Message

Set the background source size to the max we'll need + new background

Solves async reloading and rescaling the image on every horizontal resize of the window

Description of the Change

* Are there any related MPs required for this MP to build/function as expected?
No, i've set the prerequisite since it's a series i've been working on but if needed i can unchain the branches.

* Did you perform an exploratory manual test run of your code change and any related functionality?
Yes

* Did you make sure that your branch does not contain spurious tags?
Yes

* If you changed the packaging (debian), did you subscribe the ubuntu-unity team to this MP?
N/A

* If you changed the UI, has there been a design review?
N/A

Could be readonly, and a quick comment like
// avoids CPU scaling when window size changes
does no harm.

This will increase GPU memory pressure, but if that becomes an issue, we can pursue texture compression

I agree with a square asset it'd be better but this patch still improves a lot the regular resizing case in which most of the times you're not changing the anchors.fill.width > anchors.fill.height condition

Will do in silo
* Did CI run pass? If not, please explain why.
Except for broken xenial AP :/
* Did you make sure that the branch does not contain spurious tags?
Yes

I dislike that it's such a huge image. But the QML approach is sound

Use the thumbnailer to load the dash background

In the worst case (not in cache) we're a bit slower since we need to go through some extra steps for the resizing
but hopefully most of the cases the file will be in cache and we save the resizing on boot

no need for the substr
