XYF_DISPLAY_OPENGL is a C++ program which reads XYF information defining points and faces in 2D, and draws a picture using OPENGL.
The point and face information is stored in a pair of files, called the XYF format. Essentially, the first file stores a list of point coordinates, and the second lists point indices which can be connected to form faces.
