In the early days of Gio, FrameEvent was part of package app. It was moved to package system to enable layout.NewContext be a convenient short-hand for constructing a layout. However, it seems the better design to leave FrameEvent (and Insets) in package app, and move layout.NewContext there as well. More importantly, the move allows us to replace the event.Queue interface with a concrete type. Signed-off-by: Elias Naur <mail@eliasnaur.com>
