Cyan on slate, the accent the desktop app already uses. Adaptive vectors for
Android 8+ - background covering the full 108 units since the launcher applies
its own mask, foreground kept inside the central 66 that no mask can crop -
plus a monochrome layer for Android 13 themed icons, where the keyhole has to
be a hole in the path rather than a shape in another colour.
PNGs for older launchers come from make-icons.ps1, same drawing, and carry
their own rounded square since nothing masks them.
They are copied over Delphi's in repack-apk.ps1, for the same reason as
libsk4d.so: the Android_LauncherIcon and Android_AdaptiveIcon properties ought
to be enough, and nothing deploys them here.
