By "hint," do you actually mean the 'detail' parameter that gets
passed on to gtk_paint_*()? Simply changing that would break a lot of
themes that currently don't know how to handle the new 'detail'.

Again, I asume you mean the 'detail' here. I won't make any promises,
but I'll consider documenting it.
