Sure

At first I thought this was a ABI break but it was questioned in the
public IRC and the SpiceUsbDeviceWidget should not be subclassed, so
this should be fine. The chat is below for reference.

pgrunt | i have this patch https://paste.fedoraproject.org/.. is it abi
         break ? SpiceUsbDeviceWidget is publically a GtkWidget
         https://www.spice-space.org/api/spice-gtk/spice-gtk-SpiceUsbDeviceWidget.html,
         but internally I am changing it from GtkBox to GtkContainer, so
         binary is different api is same
teuf   | yeah, depends if we consider it a valid/likely use case to
         derive from SpiceUsbDeviceWidget or not
teuf   | (ie whether G_DECLARE_FINAL_TYPE could be used in the header or
         not)
pgrunt | hm, it should be final
teuf   | note that it's glib 2.44+ only
pgrunt | well i can keep the type GtkBox and use the gtk_container api
         anyway

It is horizontal grid but you are set column space. I guess it should be
_row_spacing() - although I can't see any problem in my test.

Likely I don't see any issue because of row-spacing here

Other than that, looks good
