Tech for "texdemo.bmp"

This was a simple file created for demonstrating texture mapping and all the other 
features of the raytracer to the TA's. 2d bitmaps were mapped to box, sphere, cylinder, 
and cone surfaces. Then a lens was added to demonstrate refraction of texture surfaces 
and the scene was rendered with recursion depth 3 and supersampled antialiasing. 
The texture maps were horizontal stripes for the cylinders and a Mercator Projection 
world map for the box and sphere. No special techniques were used; the objects and lights 
were simply positioned in a way looks cool.
