GL will run across the entire product line, including the 730.  It is code
compatible, with certain exceptions, mostly related to the fact that IBM GL
runs through X (as opposed to SGI's, which uses NeWS).  For example, 
the mapcolor() call shouldn't be used because mapcolors() can do colormap 
changes 4096 times as fast.

An additional header file, gl/glport.h, is also included to help in porting
programs with obsolete function calls, and can be used to ease the porting     
process.
