set_can_shrink

If set to true, the this can be made smaller than its contents.

The contents will then be scaled down when rendering.

If you want to still force a minimum size manually, consider using [method@Gtk.Widget.set_size_request].

Also of note is that a similar function for growing does not exist because the grow behavior can be controlled via [ method@Gtk.Widget.set_halign] and [method@Gtk.Widget.set_valign].

Parameters:

this	a `GtkPicture`
can_shrink	if this can be made smaller than its contents
