[Insight-developers] ImageViewer working

[George Stetten]

Hi Luis,

The official GLUT website is

http://www.opengl.org/developers/documentation/glut.html?glut#first_hit

GLUT was originally written by Mark Kilgard at SGI, although I believe 
Nate Robins maintains the code now.  
When I showed GlutMaster to Mark a few years back, he liked the 
simplicity of it and added a link to the official website.
Last time I checked, GlutMaster was getting about 10 hits per day, 
though some people may think it is an exercise machine.
The official website for GlutMaster is
