We had a short discussion about an effect that I observed with very large
height_fields and a very close camera position. It seems that POV internally
uses a machine accurancy of more than 0.00003. For most scenes it is sufficient
but for some not. With 64 bit floats the machine accurancy should be a little
bit smaller, but there will be a trade-off with the general rendering time. So I
will add a global setting of this value to the wish list for future
POV-versions.

Best regards,
Michael
