GLUT 3.4 is an incremental release. An Ada binding for SGI machines is included along with an Ada example. Many new sample programs. Several such as dinoshade.c demonstrate real-time rendering techniques relevant for games. Examples using Sam Leffler's libtiff library for loading, drawing and writing TIFF image files. GLUT version of the facial animation "geoview" decibed in the Parke and Water's book "Computer Facial Animation". New API interfaces to be made part of the GLUT 4 API update (not yet fully finalized though). glutInitDisplayMode for example. Improved portability and a few bug fixes.
