driver (which doesn't use GD), each cell is an "unsigned int"
(typically 4 bytes), regardless of whether GRASS_TRUECOLOR is set.If there was sufficient demand, I suppose that we could have separate
8-bit and 24-bit PNG drivers. Whatever the OS limitations, a version
which used one byte per cell would allow for images four times as
large as one which used four bytes per cell.--

Thanks, Glynn
In some rare cases I suppose the 8-bit driver would come useful.
