How do I "copy the default style to it"? Do I have to copy
every single field of the struct? That seems like a lot of
work for changing only the font in one widget.

Is there any reason for not supplying a new

GtkStyle *gtk_style_new( GtkStyle* template );

function, which would copy the field and you could
then selectivly change the field you want to change.

Apart from that, I don't think that the font should
be in the style struct. Changing an item's font is
nothing unusual. Changing the style of all item seems
like a drastic measure.
