Subject: [PATCH] appDisplay: Set Adjustment value after allocation

AllView's adaptToSize is called as part of viewStack allocation vfunc, and this
makes the adjustment value to be reset while relayouting.

So, fix this by delaying this using the Meta later that we already had for
pageIndicators operations.
