The minimum size corresponds to the limitations the toplevel can be shrunk
to, without resulting in incorrect painting. A user of a GdkToplevel should
calculate these given both the existing size, and the bounds retrieved from
the GdkToplevelSize object.
The minimum size should be within the bounds (see
[method@Gdk.ToplevelSize.get_bounds]).
