The CardView extends FrameLayout. This layout has some problems with
margins: http://stackoverflow.com/questions/5401952/framelayout-margin-not-working.
These can be overcome in most situations by swithcing from a margin to
some padding on the child view. The reason it is okay to do this in
most cases is because the child view is usually a layout such as a
ConstraintLayout anyway. For such cases, the difference between margin
and padding is not much different, because there are usually not any
background colours or borders applied (where padding vs margin would
usually make a difference).
Things that are still not right:
* BottomNavigationView doesn't read out the title of items when selected.

* TTS reader combines the app name and summary without a pause which is jarring.
* Touching the background of the recycler view in the categories view reads all category names.
* Likely other problems too.
Draws two rows of triangles, each coloured randomly according to
the dominant colour in the apps icon.
Given that the colour is probably assigned to the FeatureImage in response to
a network request finally downloading an image, there is a period of no feature
image. After the colour is provided, then if it is set instantly it tends to
look jerky. This eases in the colouring of the feature image.
Smooshes the recently updated and recently added lists into one,
and adds a status line under each app saying which of the two it
is (i.e. "Recnelty Updated" or "Whats New".
