Albrecht Schlosser b2a41e08c3 Introduce Fl_Flex::need_layout() to optimize layout calculation
This is intended to reduce layout calculation and resizing of child
widgets until necessary before the Fl_Flex widget and all its
children are drawn in Fl_Flex::draw().

With this commit users no longer need to call layout() to layout the
Fl_Flex widget and its children properly unless they change widget
sizes or show/hide children.

README - Fast Light Tool Kit (FLTK) Version 1.4.0

WHAT IS FLTK?

The Fast Light Tool Kit is a cross-platform C++ GUI toolkit for 
UNIX®/Linux® (X11 or Wayland), Microsoft® Windows®, and macOS®.
FLTK provides modern GUI functionality without the bloat and
supports 3D graphics via OpenGL® and its built-in GLUT
emulation. It was originally developed by Mr. Bill Spitzak
and is currently maintained by a small group of developers
across the world with a central repository on GitHub.

For more information see README.txt:
