Regarding the "Re: Make child widget doesn't erase borders ?"
thread on fltk.general (ending 12/08/2007), it was determined that it's pretty hard to make a group clip its children.

Seems it would help folks if Fl_Group had an easy way for to let the user easily turn on clipping for the group's children.

Might be useful if Fl_Group had two new methods:

             clip(flag): enable/disable clipping. If enabled, by default
             it would clip to the widget's own xywh, so a group could
             be a child of a window, and children would clip within that
             region.

             clip(x,y,w,h): set the actual clip region for drawing
             children, so it can be smaller than xywh. If set, it would
             enable an fl_push/pop_clip around the draw_children() call.

Mike's comments on fltk.development were:

    "This should be pretty straight forward."

Fixed in Subversion repository.

Only a clip on/off method was implemented, as an X,Y,W,H method would not be binary-compatible.

That said, subclasses can do:

    fl_push_clip(X,Y,W,H);
    draw_children();
    fl_pop_clip();

when they need different kinds of clipping.
