[GTK] Crash due to empty drag image during drag-and-drop
https://bugs.webkit.org/show_bug.cgi?id=142671
Reviewed by Philippe Normand.
Return early from ImageBuffer constructor if an empty size is
given. This is a speculative fix for a crash while starting a drag
and drop operation, that I haven't been able to reproduce.
