Hi.

This is the fourth in a series of Stupid Picasso Tricks.  Version 1 of iob
displays randomly colored, Gouraud-shaded Imagine objects on a 24-bit 640x480
Picasso II screen using a z-buffer.  The effect is quite psychedelic (a 60's
term which may be loosely translated as "way cool").

iob takes one parameter, the name of an Imagine object to display.  There is
no default.  Feed it an object.  :-)  If it can't find the object, the object
is invalid, it can't allocate enough memory, or whatever, it will print an
error message and exit.  Once the object has been drawn, and you are done
looking at it, exit using a mouse click or key.

This version has no control over the viewing direction - you look at the object
with +X pointing right, +Y pointing down, and +Z pointing into the screen.  It
gets scaled so it fits entirely on the screen and in the z-buffer.  You have
equally little control over the color selection (none).  Each corner of each
triangle is quite random.  Perspective is not considered.

Thanks to Steve Worley for his ongoing support, and to Glenn Lewis for the
use of his T3D library routines.

Have fun!
