NAME
====
  vg_window_flush() - flush out window to visible screen


SYNOPSIS
========
  void vg_window_flush(void)


DESCRIPTION
===========
  All output to the window is not shown until you flush it out
  with vg_window_flush().
  This is an expensive function, dependend on how many pixels have to be drawn
  (e.g. if using a higher window scaling factor, refer to vg_window_open()),
  therefore don't use it more than one time per game-loop.


RETURN VALUE
============
  No value is returned.
