Well, an hf_gray_24 function would require a new image format: one in which each
channel stores 24 bits of color information, for a total of 72 bits for the
entire image. AFAIK, povray only supports a maximum of 16 bits-per-color in a
handful of formats (PNG is one of them).
The pigment I created will generate 24 bits of heightfield data in 8
bits-per-color images (the most common format), and 48 bits of heightfield data
in 16 bits-per-color images.
