Issue #11114: Re-center Animation Playback display
This patch attempts to resolve issue #11114 (closed).
During the GAction port, we removed gtk_alignment_new ()
from the
Animation Playback plug-in as it was deprecated in GTK 3.14.
However, this caused the drawing area to be put on the left side of
the window.
This patch reimplements the alignment feature using gtk_widget_set_halign ()
and gtk_widget_set_valign ()
, to keep the animation in the center of the dialogue.
