Attached foo.cxx program shows the focus box is drawing its corners outside of the widget, living 'digital drit' behind on the window background.

Probably the focus_box code needs to bring in the left and right edges a bit if the box() type is either of these:

     FL_ROUND_UP_BOX
     FL_ROUND_DOWN_BOX

Those seem to be the only rounded boxes that have UP/DOWN versions affected by this problem, as only box types with an up/down option make them useful for buttons, and thus susceptible to focus boxes.

I think FLTK uses an internal array to account for box border widths; maybe a similar technique can be used to recommend focus box sizing..?

Possibly the "focus box" can be drawn curved using the same algorithm that draws the curved box, so that the focus box stays within the curved area.
