Use screen crop for owned popup windows

desktopIndependentWindow composites owned popups together with their
parent window and scales the group to the popup's size. Detect the case
at pick time — another window from the same app overlapping the picked
one — and capture the screen crop with a rounded mask instead, which
contains only the popup.
