Raw volume data size 256x64x256

doghead.x - AVS format image of my pet dog at my birthday party.
	Raw image size is  470x532. The AVS image format is used
	because it is very simple:

	first 4 bytes: width of image
	second 4 bytes: height of image
	remaining bytes: argbargb...

	Note that the AVS image format is a non-compressed format.

	The only image format converter I know of is at SDSC
	in ftp.sdsc.edu:pub/sdsc/graphics/imtools, and is called
	"imconv." Pre-built binaries are available for most
	platforms, except Windows (sorry).

	A JPEG version of the image is included for your edification
	(in fact, imconv was used to convert from JPEG to AVS).
