GTK4 works in logical points while Cairo works in pixels, causing images to appear smaller at HiDPI scaling. Using GtkPicture (instead of GtkImage) correctly maps the pixbuf to the right display size. This is the same fix applied to Button (eclipse-platform#3323 ) and Label (eclipse-platform#2766 ) for the same reason.

Approved (for when master reopens)
Gtk 4 works in logical points while Cairo works in pixel thus this is needed for proper size of the pixbuf scale to the original image size. This makes Button consistent with Label, which already uses GtkPicture for the same reason (see commit eclipse-platform#2766 ). Also fix a memory leak in Label where the GdkTexture created by gdk_texture_new_for_pixbuf() was not unreffed after being handed to gtk_picture_set_paintable().
