32 This program draws a box and a few line segments, and generates a
33 radial blur outward from it. This creates flowing field effects.
35 This is done by rendering the scene into a small texture, then
36 repeatedly rendering increasingly-enlarged and increasingly-transparent
37 versions of that texture onto the frame buffer. As such, it's quite
38 graphics intensive: don't bother trying to run this if you don't have
39 hardware-accelerated OpenGL texture support. It will hurt your
