Refactor and simplify "arrow drawing" in widgets
"Arrows" in widgets are those GUI elements mostly represented by
triangles pointing in a particular direction as in scrollbars,
choice widgets, some menus, valuators and Fl_Counter widgets.
The code has been simplified and standardized such that all these
GUI elements are drawn identically per FLTK scheme.
Widget authors no longer need to write code to calculate arrow sizes
and draw polygons etc.
Different schemes can and do implement different drawing functions.
Todo: see comments "FIXME_ARROW" in src/Fl_Menu_Button.cxx and
src/Fl_Menu.cxx
