Fix lints that have accumulated over time.
Apparently Android Studio just...stopped using lints. For no reason. I
had to upgrade to the beta version to actually get lints.
Unify the background state layers of the entire app by overriding
colorControlHighlight.
Lots of components still use it, so it's beneficial to make it
consistent with the rest of the app theming.
Set the enforce*BarContrast methods to false above API 29, so we can
use fully transparent navigation and status bars.
Previously, we used a mostly transparent color for such, but now, we
can use a completely transparent color without it being changed to
match contrast.
Post widget responsive behavior back to Android 11 and below. This is
not the nicest solution [mostly since the UI flickers when resizing],
but it seems to work well enough.
Modify the minimal wdiget so that it can work on Android 11 and below.
Was not actually that hard, mostly changing layouts around all things
considered. This also splits up the default view and the main widget
views, which makes managing UI state much easier.
