Folder blur: while a folder is open on the home screen, what is behind it
is blurred, icons and widgets through a RenderEffect and the wallpaper
through the launcher surface's background blur. It is a new input of the
depth controller (folderBlur, 0 to 1), because that controller already
owns both kinds of blur and cleared anything set past it on every frame
of the folder's wallpaper zoom. The folder's spring animation drives it in
step with the dimming, and the places that reset the dimming reset it too.
It works with the wallpaper depth effect switched off, without bringing
the folder's wallpaper zoom along. Setting: Folders > Blur behind open
folders, on by default (flexera_folder_blur). Folders in the app list are
left as they were.
Dock: with the dock switched off the hotseat has no height, but its icons
were still drawn just below the screen edge, and the 97.5% zoom-out behind
an open folder brought their tops into view. One more alpha channel on
the icons hides them.
Checked on the emulator (Android 17 image, window blur available): open,
close by tap outside, Back and Home, an app started from the folder, sleep
and wake, the setting off, and the depth effect off.
