Widgets of other apps used to fill their cells minus Launcher3's widget
padding, which is a few pixels wider than the icons' edges and reaches down
into the room kept for icon labels; on the owner's phone they hung about
13 px past the icons sideways and 40 px below. Now the room a widget keeps in
its cells is the distance from the cell edges to the icon edges, worked out
as IconFrame does for the launcher's own widgets, so every widget's edges
meet the edges of the icons around it.
The one function (FlexeraWidgets.appWidgetPadding) is used for the layout,
for the size the app is told, for the drop animation and through
WidgetSizes for previews. The cells a widget needs are still worked out
with Launcher3's padding, so no widget changes its cell count. A new switch
under Settings, Home screen, Widgets ("Line up with icons", on by default)
turns it off; Lawnchair's Widget padding slider shows only then.
Checked on the emulator against lines drawn at the icon edges: Google
Calendar's widgets meet them within 2 px; Google Clock's sits about 20 px
inside, because it draws an empty margin of its own.
