This would not solve the real problem. The fact is that with the
default theme, different sizes are available, but lightdm-gtk-greeter
always choose a small one.

FYI, with gtk3-icon-browser from the gtk-3-examples package, I can
see that the Symbolic/Other icons are available in the following
sizes:

16x16 24x24 32x32 48x48 64x64

If gtk3-icon-browser can select the size in the current theme, why
can't lightdm-gtk-greeter do this?

Note: I suppose that the gtk-icon-sizes solution doesn't work because
it is no longer supported by GTK3, as documented:

  https://developer.gnome.org/gtk3/stable/GtkSettings.html#GtkSettings--gtk-icon-sizes

"GtkSettings:gtk-icon-sizes has been deprecated since version 3.10 and
should not be used in newly-written code.
This setting is ignored."
