Run 2d-GL programs with standard X11 routines
Ygl is an graphics library that emulates the routines of SGI's GL (sometimes called IRIS GL). Please note that GL is different from OpenGL. Ygl is very simple to use, and very fast. The 2D routines are built around the standard X11 libraries and reported to be faster than GL itself. This release will also work with FORTRAN code and has been built with 3D support. The library therefore requires the use of the OpenGL libraries.
