This forum thread describes some of the pitfalls of using paint programs
to create heightfields.

Some of this information should probably be incorporated into the
documentation.

I'm not sure it's the duty of the official POV-Ray documentation to
comment on the pixel bit depth capabilities of third-party image manipulation
programs.

But the docs do say, "The GIF, PNG, PGM, TIFF and possibly SYS format
files are the only ones that can be created using a standard paint
program." This misrepresentation should be clarified.

Oops. Forgot this bit too: "Because PNG files can store up to 16 bits in
grayscale images they will be as smooth as TGA and PPM images."

Maybe a better place would be the TAG Questions and Tips that I'm in the
process of migrating over to the Wiki!
BTW: no content there yet .... it's still on the test bed. I will post a
message here when it's done.
