commit 89bb8cf750c586b5b291f2fd90d204791650dae5
Author: Werner Hoch <werner.ho@xxxxxx>

    gschem: redraw empty preview on configure events [#2159047]
    
    If the preview widget contained an empty page, the redraw failed. In
    the preview_event_configure() function the function a_zoom_extents()
    returns without drawing if there are no objects on the page. Thus I've
    added a complement logic to redraw the background of the preview if
    required.
    
    (cherry picked from commit 87a19a19e52a37f8ad14ae0c4c68f3292b0c3285)
