This is a basic previewer for art, written using the vogle graphics
library. It gives a wireframe rendition of the scene to be rendered.

usage:

	artview scene_file xpixels ypixels

	where xpixels and ypixels are the size of the image, this
	will produce (where possible) a VOGLE window of this size
	to give a better idea of how the view will look.

Bewarned! This is still under development, and the current version
was done in a hurry. It doesn't do strips (for example)...

The environment variable VDEVICE needs to be set to the device being
used (e.g, "sun", "apollo", "X11", etc..).
