/* Flags/Depth example:

	NOTE: for planar images, the depth is the number of planes, not the
				number of colours.

	IMFF_PLANAR and 2 == 4 colour planar image

	IMFF_PLANAR | IMFF_HAM8 and 8 == 256 colour planar image in HAM8 mode.

	IMFF_CHUNKY and 24 == 24 Bit RGB pixels.

	IMFF_CHUNKY and 18 == 18 Bit RGB pixels.

	IMFF_PLANAR and 24 == 24 Bit planar (IFF24).

	If IMFF_PALETTE is set, then the image is palette mapped, eg gif

	If IMFF_GREY is set, the the image is greyscale and not colour.
