[gtksourceview/wip/chergert/gsv-gtk4: 76/117] completion: port from GdkPixbuf to GdkTexture

commit b9873d23ec32845b637aa61218db4dd6c0fd5af1
Author: Christian Hergert <chergert redhat com>
Date:   Wed Jan 15 14:05:49 2020 -0800

    completion: port from GdkPixbuf to GdkTexture
    
    We want to use GdkTexture instead of GdkPixbuf so that the widget snapshot
    code can cache nodes and/or textures on the GPU.
