	* opengl/gl-render.h: Make sure windows.h is included before OpenGL
	headers.

	* fltk_backend/fltk_backend.cc (class plot_window): Many changes
	to use figure::properties instead of figure handle to reference
	the figure
	(class figure_manager): ditto
	(__fltk_redraw__): moved most of functionality into the
	figure_manager class
	(plot_window::pixel2pos): Modified to use axes::pixel2coord

	(__fltk_maxtime__): New DEFUN to allow tweaking of fltk timeout
	(__fltk_redraw__): Use fltk_maxtime as timeout
