Demo for the Mesh Camera macros for use with the new mesh_camera:
Simple demo of the UV version of the pinhole camera, for use with the smooth
modifier of the distribution method #3. It gives the same results, but it is
independant of the resolution: it allows for much smaller mesh camera sizes,
and works with standard AA too.
