PacketHandler* Source::activate (source.cc) calls
"activate $src" (ui-main.tcl) to open a source.
activate creates a decoder with "create_decoder $src".
After waiting for idle, "really_activate $src" (ui-main.cc) is called.
really_activate quits from itself if there is already one source active,
that is, only one source can be active at a time.
really_activate calls "add_active $src" to set active($src)=1 and to create
some widgets if this is the first source to activate in this channel.
After this, really_activate creates user interface widgets for the
video stamp, and calls "build.src $V(grid).$src $src 1". Then it calls
"update_decoder $src".
build.src calls attach_window (ui-main.tcl)
to bind the source to the stamp video window.
attach_window calls attach_renderer to create
a renderer and attach it to $src, and it also calls
"[$src handler] attach $target" to do that.
